U.S. Beer Sales and Schlitz´s Share<br />
<br />
== Critique ==<br />
*'''Overall impression and number of tables'''<br />
:[-] As one can see, the overall graphic of "U.S. Beer Sales and Schlitz's Share" consists of two separated tables. One table describes the "U.S. Beer Sales" and remains in the back while the other one describes the "Schlitz's Share" and comes to stay in the front. This makes the overall graphic difficult to understand. In the first place it is not obvious what it should communicate.<br />
:[-] Furthermore the two tables are using different styles. The "U.S. Beer Sales" are described by the use of barrels but the "Schlitz's Share" is indicated by bars even though both tables share the same object (millions of barrels).<br />
:[-] The contrast between the two tables isn't really good. The barrels are white and the bars are black. Both tables have outstanding appearances. As mentioned above, it is not clear what's the meaning of the overall graphic.<br />
<br />
*'''Layer/Structure'''<br />
:[+] Concerning the layers (data, supporting components, background) of the graphic, one can see that the data layer surely does emphasize from the background in both tables.<br />
:[+] Both the tick marks and the corresponding labels, acting as supporting components of the graphic, are good. They are thin but not too small to read.<br />
:[-] It is not a good idea to use those barrels to indicate definite information. They are indeed representative for the objective of the graphic and it would be a nice designing idea. But the observer will finally not be able to have a clue what the graphic communicates. It is not clear whether the height or the actual volume of such a barrel delivers the necessary information. Even if it would be clear both the height and the volume cannot be read off correctly.<br />
:[-] The year dates of the "U.S. Beer Sales" must not be placed within the graphic itself but down on the x-axis.<br />
<br />
*'''Data-Ink ratio'''<br />
:[-] As already mentioned before, barrels are indeed representative for the objective of the graphic. But in general it is not necessary to use the objective of a graphic as a design. To understand that it is beer what the graphic is about, the headline would be enough. The barrels, being volumetric objects, are hard to interpret and are dispensable padding for they have nothing to do with the actual cause of the figure - the comparison of the data. Furthermore, the barrels aren't standing beside each other but overlapse partially.<br />
:[-] The two scales (y-axis) project a different value range and value measure. The zero value at the base is missing resp. a hint for the scale not beginning with zero.<br />
:[-] The method of using barrels as a design produces a wrong impression at a glance. There were 160 millions of barrels sold in the year 1978 and almost 120 millions back in the year 1970. These are 25 percent of difference but if one takes a look at the two barrels he/she can see that the 1978-barrel is actually much bigger than the one that indicates 1970.<br />
<br />
*'''Visual clutter'''<br />
:[-] One can see that the table showing "Schlitz's Share" uses bars that share the same texture. There is no white space in between. This produces visual clutter and makes it difficult for the observer to distinguish between the different bars.<br />
:[-] The texture consists of a label that must not be part of the table.<br />
:[-] The first and the last bars are unnecessarily sloped.<br />
<br />
== Correction of Table ==<br />
<br />
[[Image:good-graph_beer_3.jpg]]<br />
<br />
<br />
*'''Improvements'''<br />
<br />
:[+] First we decided that both tables had to be combined into one, to cleary show the viewer that those two tables are semantically linked together, which does no fully come out in the original graphic.<br />
:[+] To assist the viewer when comparing the two data-rows we equaled both scales, so that also the size of each bar and not only the label on the axis can be compared. Because for a quick overview it is easier to compare just the size of one bar, than the correspondnig values.<br />
:[+] We start our scales with 0 so the sizes of the bars are now in the correct relation to each other, in contrast to the original graphic where for example 160 million barrels is about five times bigger than 120 million barrels, which could communicate a wrong view of the underlying data.<br />
:[+] To further improve the readability of the graph we decided to use simple bars instead of the original used barrels. Most viewers are more familiar with such visualization objects, and it simply is easier to find out the actual value of an bar compared to the barrel-visualization in the original graphic. <br />
:[+] We use gridlines in the background of the graph to support the user when trying to find out the value of an bar far off the ordinate. We decided to use drawn through gridlines instead of possibly addind an second scale at the most right end of the graph, because adding a second axis would also mean to add 9 more numerical values to the graph that don't offer new information but use ink (data-ink ration) and also might unnecessary overfill the graph.<br />

U.S. Beer Sales and Schlitz´s Share<br />
<br />
== Critique ==<br />
*'''Overall impression and number of tables'''<br />
:[-] As one can see, the overall graphic of "U.S. Beer Sales and Schlitz's Share" consists of two separated tables. One table describes the "U.S. Beer Sales" and remains in the back while the other one describes the "Schlitz's Share" and comes to stay in the front. This makes the overall graphic difficult to understand. In the first place it is not obvious what it should communicate.<br />
:[-] Furthermore the two tables are using different styles. The "U.S. Beer Sales" are described by the use of barrels but the "Schlitz's Share" is indicated by bars even though both tables share the same object (millions of barrels).<br />
:[-] The contrast between the two tables isn't really good. The barrels are white and the bars are black. Both tables have outstanding appearances. As mentioned above, it is not clear what's the meaning of the overall graphic.<br />
<br />
*'''Layer/Structure'''<br />
:[+] Concerning the layers (data, supporting components, background) of the graphic, one can see that the data layer surely does emphasize from the background in both tables.<br />
:[+] Both the tick marks and the corresponding labels, acting as supporting components of the graphic, are good. They are thin but not too small to read.<br />
:[-] It is not a good idea to use those barrels to indicate definite information. They are indeed representative for the objective of the graphic and it would be a nice designing idea. But the observer will finally not be able to have a clue what the graphic communicates. It is not clear whether the height or the actual volume of such a barrel delivers the necessary information. Even if it would be clear both the height and the volume cannot be read off correctly.<br />
:[-] The year dates of the "U.S. Beer Sales" must not be placed within the graphic itself but down on the x-axis.<br />
<br />
*'''Data-Ink ratio'''<br />
:[-] As already mentioned before, barrels are representative for the objective of the graphic. But in general it is not necessary to use the objective of a graphic as an design those barrels to indicate the actual amount of beer - in this case. To In this case, making the barrels bigger as the amount of sold beer grows is intuitive and good.<br />
<br />
''Um zu verstehen, dass es sich um Bier handelt, dafür reicht die Überschrift. Die Fässer als volumetrische Objekte sind schwer zu interpretieren und sind überflüssiges Beiwerk, da sie mit dem eigentlichen Zweck der Grafik - Vergleich der Daten - nichts zu tun haben.''<br />
<br />
''Die Fässer stehen zudem nicht nebeneinander, sondern verdecken einander teilweise.''<br />
<br />
''Die beiden Skalen (Y-Achsen) bilden einen unterschiedlichen Wertebereich und Wertemaßstab ab. Es fehlt der Nullwert an der Basis bzw. ein Hinweis, dass die Skala nicht bei Null beginnt.''<br />
<br />
:[-] Nevertheless this method produces a wrong impression at a glance. There were 160 millions of barrels sold in the year 1978 and almost 120 millions back in the year 1970. These are 25 percent of difference but if one takes a look at the two barrels he/she can see that the 1978-barrel is actually much bigger than the one that indicates 1970.<br />

*'''Visual clutter'''<br />
:[-] One can see that the table showing "Schlitz's Share" uses bars that share the same texture. There is no white space in between. This produces visual clutter and makes it difficult for the observer to distinguish between the different bars.<br />
:[-] The texture consists of a label that must not be part of the table.<br />
:[-] The first and the last bars are unnecessarily sloped.<br />

<br />
*'''Improvements'''<br />
:[+] First we decided that both tables had to be combined into one, to cleary show the viewer that those two tables are semantically linked together, which does no fully come out in the original graphic.<br />
:[+] To assist the viewer when comparing the two data-rows we equaled both scales, so that also the size of each bar and not only the label on the axis can be compared. Because for a quick overview it is easier to compare just the size of one bar, than the correspondnig values.<br />
:[+] We start our scales with 0 so the sizes of the bars are now in the correct relation to each other, in contrast to the original graphic where for example 160 million barrels is about five times bigger than 120 million barrels, which could communicate a wrong view of the underlying data.<br />
:[+] To further improve the readability of the graph we decided to use simple bars instead of the original used barrels. Most viewers are more familiar with such visualization objects, and it simply is easier to find out the actual value of an bar compared to the barrel-visualization in the original graphic. <br />
:[+] We use gridlines in the background of the graph to support the user when trying to find out the value of an bar far off the ordinate. We decided to use drawn through gridlines instead of possibly addind an second scale at the most right end of the graph, because adding a second axis would also mean to add 9 more numerical values to the graph that don't offer new information but use ink (data-ink ration) and also might unnecessary overfill the graph.<br />

U.S. Beer Sales and Schlitz´s Share<br />
<br />
== Critique ==<br />
*'''Overall impression and number of tables'''<br />
:[-] As one can see, the overall graphic of "U.S. Beer Sales and Schlitz's Share" consists of two separated tables. One table describes the "U.S. Beer Sales" and remains in the back while the other one describes the "Schlitz's Share" and comes to stay in the front. This makes the overall graphic difficult to understand. In the first place it is not obvious what it should communicate.<br />
:[-] Furthermore the two tables are using different styles. The "U.S. Beer Sales" are described by the use of barrels but the "Schlitz's Share" is indicated by bars even though both tables share the same object (millions of barrels).<br />
:[-] The contrast between the two tables isn't really good. The barrels are white and the bars are black. Both tables have outstanding appearances. As mentioned above, it is not clear what's the meaning of the overall graphic.<br />
<br />
*'''Layer/Structure'''<br />
:[+] Concerning the layers (data, supporting components, background) of the graphic, one can see that the data layer surely does emphasize from the background in both tables.<br />
:[+] The grid lines, acting as supporting components of the graphic, are good. They are thin and their labels are not too small to read.<br />
:[-] Of course, the background layer could be much brighter to make the data layer clearer.<br />
:[-] It is not a good idea to use those barrels to indicate definite information. They are indeed representative for the objective of the graphic but for the observer it is very difficult to see the actual height of one barrel.<br />
<br />
*'''Data-Ink ratio'''<br />
:[+] As already mentioned before, barrels are representative for the objective of the graphic. In this case making the barrels bigger is intuitive and good.<br />
:[-] Nevertheless this method produces a wrong impression at a glance. There were 160 millions of barrels sold in the year 1978 and almost 120 millions back in the year 1970. These are 25 percent of difference but if you take a look at the two barrels you can see that the 1978-barrel is actually much bigger than the one that indicates 1970.<br />
<br />
*'''Visual clutter'''<br />
:[-] One can see that the table showing "Schlitz's Share" uses bars that share the same texture. This produces visual clutter and makes it difficult to distinguish between the different bars.<br />
:[-] The first and the last bars are unnecessarily sloped.<br />

<div>== Brief definition ==<br />
The term flow visualization describes the process of making the physics of fluid flows visible.<br />
<br />
== What is flow visualization? ==<br />
As we are human beings who live on earth, we are familiar with all the elements and forces that affect our lives constantly. Thus most of us roughly know some things about fluids too. Everyone has at least once seen how water whirls in a bathtub when it runs out or how wind blows leaves around in autumn forming kind of a small vortex. We all know pictures of a cloud formed like a mushroom after the explosion of an atomic bomb. Obviously we are acquainted with the flow of fluids though we can’t actually see many of them because they are transparent, i.e. air, water or gas. We do also know how to describe the fluid motion by mathematical equations but the problem is that these are far too difficult to be computed by humans. We can only try to solve these equations via using numerical calculators, i.e. very fast computer algorithms. But even the numerical results are only estimations and may not correspond to natural processes until they have been approved by physical experiments. So, in order to understand what is going on we need to find ways to make visible what cannot be actually perceived by the human eye.<br />
<br />
In fact, there are several ways how to do this. Generally we can divide into two main methods:<br />

* Physical method. By the use of wind in a tunnel combined with small particles, i.e. smoke, oil, etc. one can make the motion of a fluid, i.e. air visible. Figure 1 shows how such a windtunnel works. From a definite source wind is imitated by fans and directed at the airfoil. In this case small smoke particles are used to make the flow of the air visible. We can actually perceive how the air moves around the airfoil and forms vortices at the bottom and the back of it. These method is very useful in designing aircrafts and especially airfoils.<br />
* Computational method, i.e. computational fluid dynamics. As already mentioned above, the motion of fluids as a whole can be expressed by mathematical equations which can be estimated numerically. Thus even supercomputers would take a long time to solve the equations and the solution would only be an estimation of the definite problem, more accurate methods needed to be discovered. One approach is to discretize the spatial domain into small cells so every single cell can be computed separately. Using this method one gets a mesh grid of the definite fluid motion. Figure 2 shows how such a mesh grid looks like in practice. NASA is testing complex scenarios of its space shuttles like return-to-launch-site and transatlantic abort maneuvers by the use of computational fluid dynamics. The image shows the surface pressure distribution at the speed of Mach 15. Figure 3 shows another shape of how computers can be used for flow visualization. With an accurate software packet, i.e. FieldView, streamlines around a solid surface can be computed virtually without the use of a windtunnel.<br />

== What is flow visualization? ==<br />
As we are human beings who live on earth, we are familiar with all the elements and forces that affect our lives constantly. Thus most of us roughly know some things about fluids too. Everyone has at least once seen how water whirls in a bathtub when it runs out or how wind blows leaves around in autumn forming kind of a small vortex. We all know pictures of a cloud formed like a mushroom after the explosion of an atomic bomb. Obviously we are acquainted with the flow of fluids though we can’t actually see many of them because they are transparent, i.e. air, water or gas. We do also know how to describe the fluid motion by mathematical equations but the problem is that these are far too difficult to be computed by humans. We can only try to solve these equations via using numerical calculators, i.e. very fast computer algorithms. But even the numerical results are only estimations and may not correspond to natural processes until they have been approved by physical experiments. So, in order to understand what is going on we need to find ways to make visible what cannot be actually perceived by the human eye.<br />
<br />
In fact, there are several ways how to do this. Generally we can divide into two main methods:<br />

<div>== What is flow visualization? ==<br />
As we are human beings who live on earth, we are familiar with all the elements and forces that affect our lives constantly. Thus most of us roughly know some things about fluids too. Everyone has at least once seen how water whirls in a bathtub when it runs out or how wind blows leaves around in autumn forming kind of a small vortex. We all know pictures of a cloud formed like a mushroom after the explosion of an atomic bomb. Obviously we are acquainted with the flow of fluids though we can’t actually see many of them because they are transparent, i.e. air, water or gas. We do also know how to describe the fluid motion by mathematical equations but the problem is that these are far too difficult to be computed by humans.

<div>== What is flow visualization? ==<br />
As we are human beings who live on earth, we are familiar with all the elements and forces that affect our lives constantly. Thus most of us roughly know some things about fluids too. Everyone has at least once seen how water whirls in a bathtub when it runs out or how wind blows leaves around in autumn forming kind of a small vortex. We all know pictures of a cloud formed like a mushroom after the explosion of an atomic bomb. Obviously we are acquainted with the flow of fluids though we can’t actually see many of them because they are transparent, i.e. air, water or gas. We do also know how to describe the fluid motion by mathematical equations but the problem is that these are far too difficult to be computed by humans. We can only try to solve these equations via using numerical calculators, i.e. very fast computer algorithms. But even the numerical results are only estimations and may not correspond to natural processes until they have been approved by physical experiments. So, in order to understand what is going on we need to find ways to make visible what cannot be actually perceived by the human eye.<br />
== Definition ==<br />
{{Quotation|The insight into a physical process is always improved if a pattern, produced by or related to this process, can be observed by visual inspection. This becomes obvious if we think of a fluid-mechanical process where a fluid is flowing in a channel or around a solid obstacle. By observing such a flow pattern, which might be stationary or variable with time, one can get an idea of the whole development of the flow. However, most fluids, gaseous or liquid, are transparent media, and their motion remains invisible to the human eye during a direct observation. To be able to recognize the motion of the fluid, one must therefore provide a certain technique by which the flow is made visible. Such methods are called flow-visualization techniques.|[Merzkirch, 1987]}}<br />
