gcmap

This is a Python rewrite of the code used to create the Visualizing Facebook Friends visualization in 2010.

The original code was written in R and was built specifically around the Facebook dataset. This rewrite is as a Python module and is built to work on top of any dataset.

If you are looking to visualize a few (<10,000) coordinate pairs, matplotlib with basemap will be more flexible. The visualization implemented by this module is useful when the data alone are sufficient to show the geography.

The algorithm uses a heuristic which attempts to visualize the structure of the pairs rather than their relative importance. In interpreting the results, you should not come to any conclusions about the relative importance of different coordinate pairs.
