Ratings let you assess a visualisation according to:
Impact: How much a visualisation makes you take notice of it
Accuracy: How well it portrays the true data behind it
Rate visualisations according to your own impressions and expertise. We also ask you to let us know how you
rate your own level of expertise in terms of data and visualisation, so that we can filter ratings further
The World Bank has created a complex visualisation tool to make available 49 indicators for 209 countries and 18 aggregates from 1960-2007. Data includes social, economic, financial, information & technology, and environmental indicators. The visualisation is completely customizable bubble chart in the spirit of 'gapminder' and the user selects the x and y axis dimensions as well as the variable that determine the size of the bubbles and the time point to be displayed.
User can customize all aspects of the tool, variables and countries to be displayed, colours, scales and export options.
Benefits & pitfalls to avoid
Using area or volume to represent data can distort data values, and exaggerate differences between values. For example, if the radius of the circle is used to represent data values, the area of the circle will quadruple if the data values double. There is also an issue of 'perceptual scaling' - the tendency of people to underestimate areas.
Create your own
Bubble charts can be created in a range of standard data applications such as Excel.
