Teaching talk:TUW - UE InfoVis WS 2009/10 - Gruppe 03 - Aufgabe 3

Regelverletzung:

• Regel 3: Farbgebung in den gegebenen Diagrammen zwar sinnvoll, jedoch können die Diagramme besser aufgebaut werden (Balkendiagramme)
• Regel 5: Farben sind nicht gut gewählt. Speziell Rot und Grün in einem Diagramm ist nicht empfehlenswert (Farbblindheid bzgl. Unterscheidung, Regel 8)
• Regel 6: Farben sind nicht unterschiedlich genug (zB. Grün, Gelb)

• Vergleiche zwischen den Diagrammen sind nicht Aussagekräftig. Keine Angaben von Fixwerten oder prozentualen Werten.
• Kontrast zwischen Hintergrund und Vordergung ist nicht optimal gewählt (speziell für Ausdruck)
• Unnötige "non-data-ink" muss aus dem Diagrammen raus (zB. Abteilungen zwischen den Diagrammen)
• Diagramme gehören umgebaut. Momentan ist nicht klar, welche Daten heraus kommen sollen, was vergleichen wird etc.
• Diagramme sequenzieren zur Vereinfachung der Lesbarkeit (von links nach rechts, von oben nach unten)
• Eventuell die "introduction" überarbeiten, da die aufs gesamgte Bild bezogen ist und aus hier aus dem Fokus gerissen wird!
• What, When, Who, Where beachten im Diagramm

Additional Ideas/ Critics:

• Introduction mentions US, but no graph about US itself.
• No percentage on graphs. No exact values plotted --> no exact message
• Black background (no data-ink) --> bad contrast
• Is any data more important?
• Detailed legend for every graph --> may be replaced by legends included inside the graph, so reader is able to derive this info by himself

some more redesign ideas

• The black background - although it probably made sence in the original context - could be removed -> the text colored black
• The headlines background shouldn't differ a lot from the main background color, to not draw away attention from the data
• Enhance the use of ink in a way, that simmilar categories get more simmilar colors, but still having enough difference between the colors
• Rethink, if all caregories are needed. If not, add unrelevant data to the 'other' section (e.g. animal fat).
• Soften the colors of the less relevant data compared to the important one (important are: meat, cereals, ?); 'other' should be least prominent;
• Remove the decoration element in the middle of the graphs, because it just distracts.
• Text below the image: display the words referring to categories of the graphs italic.
• Hues like black and red ten k to drag more attention than others, don't ose them if this is not intended´
• Reorder th data, so that the graphs begin with the most important category, the least important at the end
• The texts written below the graphs should probalby be palced on top of them. Then they're read before the graphs more likely
• Rotated text is bad, dont use it like the years.
• Border around the graphs and their related explanations? Not good
• Possible new structure of the graphs:
  • Keep each region in a different graph. Putting them all together would lead to chaos.
  • Use a bar diagram, each bar is a category, the years are put next to each other
  • or use a line diagram instead with the years as horizontal developing. The categories are represented by different lines and different colors.
  • In both ways, the graphs shall be placed next to each other (from left to right), to make it possible to compare the values of the regions as well.
• Importance can also be communicated via thickness of the lines
• Keep size of legend the same than the text, labels
