SPREAD is a user-friendly application to analyze and visualize phylogeographic reconstructions resulting from Bayesian inference of spatio-temporal diffusion.
There is a tutorial for SPREAD online at http://www.kuleuven.be/aidslab/phylogeography/tutorial/spread_tutorial.html
Originally this program is named spread. However, there is just such a package inside Debian and thus a 'phy-' for phylogeny was prepended.

The authors of the software SPREAD are Filip Bielejec, Andrew Rambaut, Marc A. Suchard, Philippe Lemey.
