Aufgabenstellung
Zu beurteilende Grafik
Critics on the table
- Non-data ink is high :
- Shadowing and the 3-D visualization of the World Map, 3d visualization of the CO2 emissions and rising tides, these objects increase the non-data ink, thus decreasing the data-ink ratio.
- 3-D CO2 Emission Bars block some the regions which is supposed to convey important information. (Especially the regions in black)
- The icon, which aims to emphasize regions of poverty, blocks important information and de-emphasizes the data-ink, although this icon doesn't convey a precise information.
- Consequently the real message or data is not supported in the Graph, which is against the task of visualizing quantitive information.
- The data is unorganized :
- The essential message of the graph is not clear, CO2 emissions of Regions ? Heat the Poor ? or the rising tides ?
- It is not clear which data has more priority.
- The data is not sequenced, thus confusing the readers. In other words there is no direction for order in which data should be read.
