Geographic Grid Embeddings

Some pretty pictures our method produces:

The US Presidential elections in 2008 using a Geographic Grid Embedding (GGE). The visualisation that is used inside each of the cells is something like a histogram in which each block represents one electoral vote.

Some US demographics displayed using a GGE and tree-maps.

The effect of different matching algorithms on our GGE. The ``smoother'' the gradient, the better the results.
