Interesting map of commuting data.

The datashine mapping project seeks to promote and develop the use of large and open datasets amongst the social science community. A key part of this initiative is the visualisation of these data in new and informative ways to inspire new uses and generate insights.

This particular map show Scottish commuting data. Unfortunately it's quite old though as it's from the 2011 census.
