This chart indicates how the number of people in each county changes while people getting in and out of work. Map chart on the right side is scaled by population to show differences more suggestively. This way is commonly used in infographics, but in my opinion the various shapes of pieces don't give a true notion of area differences between them and so, are difficult to compare and make conclusions. While pointing at each county user can find it's real size on the map on the left side which is very helful.
Here is one more example of scaled map chart. Author used the tiles of the same size, so the chart is much more legible.
Non-UK born census populations 1951-2011
Often, it's necesarry to create several infographics to illustrate more complex data and relationship between them. Next three charts creates dataset, and to have a clear picture of information, one should understand all three charts.
1. Here, bubble chart is used to show top-ten non-uk countries of birth durnig the years 1951-2011. Size of the bubble and caption number shows emigrants number. Every bubble has a caption with the name of the country and additionally author use specific colour for each country- thanks to that user can easily compare and see changes through the years. Bubbles are placed in the coordinate system where y-axis sygnalize position in 1-10 top non-uk countries of birth, and x-axis shows year. In my opinion it's useful and well-designed infographic.
2. Bar graph illustrates the number of all other non-uk born citizens. The high of each bar is propotional to a number of people and captions shows specific numbers.
3.Pie charts shows relationships between the number of citizens born in "top-10 non-uk countries" and "all-other non-uk countries"
Population in England and Wales by ethnic group
This chart shows the number of people in each ethnic group by the proportional size of area.
Arrival timeline for a selected range of non-uk countries of birth in 2011 in England and Wales
It's more complex which shows how difficult is to show more complex data on two-dimensional surface. User need few minutes to learn how to read the chart. Lack of order in names of the countries is disadvantage in this presentation. For me it's also misleading to put data about number of people arriving in two quadrants while it could be put in one quadrant. Probably present solution looks better but understanding and comparing information become more difficult.
