Aufgabenstellung
Zu verbessernde Grafik
Positives
- colours show the regions
Critique on the existing graphic
- it is very difficult to interpret
- there is a growth in carbon emissions of 28 % but this is not shown in the graphic
- most of the datas in the circles are not assignable to specific countries
- you can't click on the circles below
- the big dotted circle is expressionless
- you can see the growth in carbon emissions in per cent only at three of the five bigest CO2 producers
- the dimension of the circles is expressionless (sometimes bigger circles for low numbers and smaller circles for high numbers)
- the sum of the numbers from the circles is not the same as the given number of the million tonnes of CO2
