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

Detailled information exists only from 2007 so it cannot be grouped according to the purpose of spent money. The details of 2007 are not included in the graphic but appear as a kind of legend.

The graphic only stresses the rising trend but no exact values within the years We can only read two amounts of money and the year numbers. Furthermore the lie factor of this graphic cannot be evaluated.

We assumed the data density to be okay if you stick with this type of visualization, since a reduction of the area size would make it not readable anymore. If visualized in another way the density could be maximized.

The big red cross in the centre is unnecessary non data ink and therefore visual clutter.

This type of visualization is not well chosen for the given type of data.

Because the circle size grows with the amount of spent money and not the sequence of years, its not acceptable to hide the Information of the year (in the inner red circle $375B), because it cannot be understood from reading the graphic.
