More than a Marker

Here's a rare non-Google map that is so good it has to get a mention.

Rennes - Visualisation de Donnees is a great mapped visualisation of demographic, employment and housing data in Rennes, France.

Data on the map is represented by small coloured map markers. However the magic happens when the user selects a neighbourhood on the map. When an area is selected the markers fly off the map and sort themselves into the appropriate categories in bar chart form.

The effect is impressive and, more importantly, vastly improves the legibility of the data.

On a slightly related subject if you are interested in using the Google Maps API to visualise data then you should check out today's Google Maps Developers Live session, Visualising Data with the Google Maps API. The session is live from 10 a.m. Pacific time. In the session Google will be explaining how they used the Maps API to visualise the Climatological Database for the World's Oceans.
