What's for dinner

=== Critics ===

A first look at the graphic "What's for dinner" does not reveal a lot about the information presented in the graphic. The title, which should summarize the graphic in short has nothing to do with the message of the image. To get the meaning you first have to read the small printing underneath the title, explaining about the connection between the destruction of the rainforest to provide more land for the grazing of cattle. Even now, knowing what is supposed to be shown, one could start thinking about the advantages of food production, having in mind that a high percentage of the worlds population is starving and in the need of food. This feeling is reinforced looking at the delicious steaks being shown in the graphic. On the other side the destruction of a vast amount of rainforest does not evoke any compassion at all. It is displayed by a sphere, which is at first filled with about 1/3th and getting a bit less filled in the other representations, but only coming close to 1/4th, which does not seam like a noticeable loss of rainforest. Also it is not obvious what the sphere stands for, it could be the world, or Brazil, or something completely different. So overall the message that is supposed to be sent with this graphic is confusing.

The graphic contains mostly non-data-ink, there are a lot of images, lines and text which are not necessary to present the data in question. It is very confusing to have a change in scale, regarding the time periods between the data. The fact that the first time segment spans 20 years and the second time segment only spans 15 years makes it hard to take the graphic seriously. To really get the information, one has to tilt his or her head in order to find out which scales the data is measured in, which is in fact in two different scales, metric tons on the one hand, square kilometres one the other. The labelling of the two different kinds of data is not only written vertically, but it also does not stick out as important. Each group of data has another type of labelling, giving information about the amount of data shown in each picture. The labelling of the steaks easily gets lost in the big picture. This is mainly because it is written in the same colour as the steaks, but is much smaller as they are. The labelling of the rainforest on the other hand also does not stick out too much, but is a bit more obvious than the labelling of the steaks. This is due to the fact, that the numbers are directly on the spheres and the color is a bright red which easily sticks out.

The used image representation is, as discussed before poorly chosen. The units of steaks shown in the images stand in no connection with the data they are supposed to represent. There is a flag sticking in one of the steaks for no obvious reason, which is useless non-data-ink. And the drastic change of existing rainforest is not obvious using a pie diagram, because this form of representation does not make it easy to notice the change over time. There are a few obvious and less obvious points the desperately need to be changed in order to impress the viewer.

Brazilian rainforest areas replaced by cattle farmland

=== Correction ===

In the above changed graphic the destruction of the rainforest has been emphasized, using pictograms instead of a pie chart. Though this might stand in conflict with the "use-less-non-data" philosophy in order to make the graphic simple and easy to understand, it is easier to get the message of the graphic at first glance without having to look at the caption. To focus on the destroyed areas, the lost trees have been marked with red crosses rather than leaving them out. This way the message greenpeace might have intended for the graphic should be delivered in a more obvious and direct way. The lines in the changed graphic were used to make the differentiation of the different years more obvious. The text of the graphic was unified and adapted to the importance of its information.

The lack of data could not be fixed, but with using the year dates as titles instead of a timeline the difference between them should be less bothering. The number of trees as well as the number of cows stand for precise units: one tree represents 100.000 square kilometres and one cow represents 500.000 metric tons. Using parts of the respective pictograms should approximate the exact values as good as possible.

Over all, it was tried to keep close to the style of the original graphic, which looks like it had the purpose to be used for public relations reasons, but changed to optimize the visual information using the data at hand.

What's for dinner

=== Critics ===

A first look at the graph "What's for dinner" does not reveal a lot about the information presented in the graph. The title, which should summarize the graph in short has nothing to do with the message of the image. To get the meaning you first have to read the small printing underneath the title, explaining about the connection between the destruction of the rainforest to provide more land for the grazing of cattle. Even now, knowing what is supposed to be shown, one could start thinking about the advantages of food production, having in mind that a high percentage of the worlds population is starving and in the need of food. This feeling is reinforced looking at the delicious steaks being shown in the graph. On the other side the destruction of a vast amount of rainforest does not evoke any compassion at all. It is displayed by a sphere, which is at first filled with about 1/3th and getting a bit less filled in the other representations, but only coming close to 1/4th, which does not seam like a noticeable loss of rainforest. Also it is not obvious what the sphere stands for, it could be the world, or Brazil, or something completely different. So overall the message that is supposed to be sent with this graph is confusing.

The graph contains mostly non-data-ink, there are a lot of images, lines and text which are not necessary to present the data in question. It is very confusing to have a change in scale, regarding the time periods between the data. The fact that the first time segment spans 20 years and the second time segment only spans 15 years makes it hard to take the graph seriously. To really get the information, one has to tilt his or her head in order to find out which scales the data is measured in, which is in fact in two different scales, metric tons on the one hand, square kilometres one the other. The labelling of the two different kinds of data is not only written vertically, but it also does not stick out as important. Each group of data has another type of labelling, giving information about the amount of data shown in each picture. The labelling of the steaks easily gets lost in the big picture. This is mainly because it is written in the same colour as the steaks, but is much smaller as they are. The labelling of the rainforest on the other hand also does not stick out too much, but is a bit more obvious than the labelling of the steaks. This is due to the fact, that the numbers are directly on the spheres and the color is a bright red which easily sticks out.

The used image representation is, as discussed before poorly chosen. The units of steaks shown in the images stand in no connection with the data they are supposed to represent. There is a flag sticking in one of the steaks for no obvious reason, which is useless non-data-ink. And the drastic change of existing rainforest is not obvious using a pie diagram, because this form of representation does not make it easy to notice the change over time. There are a few obvious and less obvious points the desperately need to be changed in order to impress the viewer.

* By following [Few, 2004a] we highlight the data through a desing process:
** Reducing the non data ink
*** Subtract unnecessary non-data ink:
*** De-emphasize and refgularize the data ink:
** Enhancing the data ink
*** Subtract unnecessary data ink
*** Emphasize the most important data ink

=== Changed Graphic ===

[[Image:Sotpg2.jpg|600px]] 

In the following changed graph we tried to emphasize the destruction of the rainforest, using pictograms instead of a pie chart. Though this might stand in conflict with the less non-data philosophy

Teaching:TUW - UE InfoVis WS 2008/09 - Gruppe 07 - Aufgabe 1 - Stick Figure

2008-11-04T17:44:11Z

UE-InfoVis0809 0201680:

==Stick Figure==

----

===Definition===

{{Quotation| A simple drawing, typically of a human body with a circle representing the head and straight lines representing the torso and limbs. | [Cynewulf, 2007]}}

In addition to the quoted definition of stick figures it is in fact also possible to represent other living creatures, using the above mentioned method, drawing a circle for the head and straight lines for the rest of the body.

[[image:journal_4.png|thumb|xkcd]]

===Recognizable representation===

Due to the fact, how easy it is to draw and understand stick figures, they are used in various surroundings. Stick figures provide a way to easily represent various situations, forms and proportions of living creatures. They are therefore used in the fields of entertainment, arcitecture and motion analysis.

[[image:Stick_figure_sample.JPG|thumb|stick figure sample]]

===Human motion patterns===

Stick figures can be used for the visual analysis and creation of human movement. This relation is used in the work of Mao, Qin and Wright, who developed a program using 2D storyboard representations of stick figures to create a 3D character animation.
{{Quotation| [...] users can depict the character actions by drawing simple stick figure key poses, with graphical motion paths and timing, which can be automatically reconstructed as continuous 3D motion. | [Mao,Qin,Wright, 2007]}}

=== Comics and Entertainment ===
Stick figures seem to be popular actors in webcomics and animations. One of the most
popular web comics starring mostly stick figures is xkcd. When used in animated
graphics or short movies the displayed stick figures often wind up dead.

Teaching:TUW - UE InfoVis WS 2008/09 - Gruppe 07 - Aufgabe 1 - Pie Chart

2008-11-04T17:24:18Z

UE-InfoVis0809 0201680:

== Pie Charts==

=== Definition ===
{{Quotation | A pie chart is a circular chart divided into sectors, illustrating relative magnitudes or frequencies or percents. In a pie chart, the size of each sector is proportional to the quantity it represents. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced. | [Wikipedia, 2008]}}

{{Quotation | A type of chart divided into sections of a circle, drawn from a single Y-axis value and used to illustrate the relationship of parts to the whole, particularly useful for emphasizing one specific element. | [Hull, 1998]}}

----

===How to use it===
Determine proportions. Find the total value for the entire category being studied and calculate
the percentage for each segment or part.

Calculate degress. Convert the percentage values for each segment into degrees relative to the
360 degrees in the circle. (For example, 12% X 360 degrees = 43 degrees)

Construct the chart. Draw a circle and divide it into appropriately sized segments.
Add labels and a title. Label each segment or add a legend to identify the segments. Then
clearly title the chart.

----

=== Crtiticism on the Pie Chart ===

[[image:PiechartsAndBars.png| thumb | Comparison of Pie Chart vs. Bar Chart]]
Though being a common method of displaying data, pie charts are not the preferred method
among statisticians and in scientific literature. While pie charts offer a good view on
how one segment is related to the whole pie the comparison of segments amongst each other
is difficult. Also a comparison by angle (as in pie charts) was shown to be percieved less
accurate than comparison by length. Using bars instead of slices improves therfore improves
the capability to compare the different segments of data.

----

===Example===
[[image:pie_chart_example.jpg|picture]]
==== Data ====
A student's life.
Hours per week.
* '''Sleeping''' '''40'''
* '''Partying''' '''15'''
* '''Eating''' '''10'''
* '''Slacking''' '''20'''
* '''Working''' '''30'''
* '''Studying''' '''20'''

----
=== Other Forms of Charts ===
Among Pie Charts, used to display percentages, other forms of charts can be used for different
purposes.
* Column Charts - Used to show comparisons between items of data. A column in the chart represents the value of one item of data.
* Bar Charts - Are very similar to column charts, except they run horizontally on the page instead of vertically like column charts.
* Line Charts - Used to show trends over time. Each line in the graph shows the changes in the value of one item of data.

== Pie Charts==

=== Definition ===
A pie chart is a circular chart divided into sectors, illustrating relative magnitudes or frequencies or percents. In a pie chart, the size of each sector is proportional to the quantity it represents. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced.

A type of chart divided into sections of a circle, drawn from a single Y-axis value and used to illustrate the relationship of parts to the whole, particularly useful for emphasizing one specific element.

----

===How to use it===
Determine proportions. Find the total value for the entire category being studied and calculate
the percentage for each segment or part.

Calculate degress. Convert the percentage values for each segment into degrees relative to the
360 degrees in the circle. (For example, 12% X 360 degrees = 43 degrees)

Construct the chart. Draw a circle and divide it into appropriately sized segments.
Add labels and a title. Label each segment or add a legend to identify the segments. Then
clearly title the chart.

----

=== Crtiticism on the Pie Chart ===

Though being a common method of displaying data, pie charts are not the preferred method
among statisticians and in scientific literature. While pie charts offer a good view on
how one segment is related to the whole pie the comparison of segments amongst each other
is difficult. Also a comparison by angle (as in pie charts) was shown to be percieved less
accurate than comparison by length. Using bars instead of slices improves therfore improves
the capability to compare the different segments of data.

==== Data ====
A student's life.
Hours per week.
* '''Sleeping''' '''40'''
* '''Partying''' '''15'''
* '''Eating''' '''10'''
* '''Slacking''' '''20'''
* '''Working''' '''30'''
* '''Studying''' '''20'''

----
=== Other Forms of Charts ===
Among Pie Charts, used to display percentages, other forms of charts can be used for different
purposes.
* Column Charts - Used to show comparisons between items of data. A column in the chart represents the value of one item of data.
* Bar Charts - Are very similar to column charts, except they run horizontally on the page instead of vertically like column charts.
* Line Charts - Used to show trends over time. Each line in the graph shows the changes in the value of one item of data.
