From Tile Pyramids to Population Pyramids

It’s actually a stacked bar chart rather than a traditional population pyramid, but the image below shows male/female population by age for all the output areas in England. The red thematic overlay is total population for every OA, which can be clicked to get the age group breakdown shown in the popup window.
This map is a variation on the original clickable OAC map and was built using a new version of the GMapCreator which contains the clickable technology. Traditionally, maps like this have been built using a server and database to translate the click on the client into a geographic area using point in polygon and then sending the query data back to the client.
