Aufgabenstellung

Zu beurteilende Grafik

Teenage births in rich nations

Criticism

Organize the Data

First nation mentioned in the graphic are the United States, before alphabetically ordered list of nations is presented. This could be useful if the most viewers of the graphic come from the US. But since this is only an assumption it might be better to put the data for the United States also to their appropriate position in the alphabetic listing.

The Role of Text

The legend describing the meaning of read circles stands inside the table. Since this might be considered the explanation for the most important data in the graph it might be better to put this legend on top of the graph such that the viewer immediately sees it.

Subtract unnecessary data ink

Filled circles increase data ink, use unfilled circles instead

Subtract unnecessary non-data ink

The Shaded rows holding the highest value for each column are not necessary. The red color of the circles focus the viewers attention already to them.

De-emphasize and regularize the remaining non-data ink

The lines used to split the columns are to strong, use neutral colors as for example a light gray.

Optimized graphic

Teenage births in rich nations

Improvements
