This is a very rich infographic that combines several visualisation types: bubble chart, population pyramid, comparative line charts, a map, pie charts and it is additionally fully annotated. The picture itself is crossed by a line (without reference axis) that communicates the main message of the infographic: the rapid population growth experienced by the UK in recent decades. The supplementary charts display information about population proportions, population densities, age and gender structure, comparison between migration related and “natural” population change, fertility rates during the last 35 years and lastly population changes by government region during 2007-08. The display is very rich and is successful at grabbing’s the reader’s attention by offering an appealing combination of related data.
Square pie/Waffle chart
This visualisation is an example of a square pie. A square is divided into 10x10 fields, and for each number, as many fields are filled in as there are percent. Consequently, the numbers remain readable by simply counting the number of fields covered by one colour. Taking a hint from squarified treemaps, the areas should also be as square as possible for better comparability.
A modification of the radar plot, it is useful in the presentation of multivariate data.
