The same technique is applied in the other dimensions presented: medals by geopolitical groups (China, EU, ex soviet republics) , by sport (swimming, athletics, gymnastics) , by GDP and by population. It also contains full information of the final medal count by country and a day-by-day gold medal count (annotated bar char in the lower half). All parts of the visualisation are commented to give an overall picture of the event.

Screenshot for 'Population projection'
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

Screenshot for 'Square pie / Waffle chart'
Data on women in information technology using 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.<br />The square pie chart is for completely flat data that adds up to 100%, whereas the treemap shows structured data: a hierarchy. They may end up looking the same, but the meaning is not.
