How many types of GIS map data file does Graphstream support?

Dear authors,
I notice that in the link http://graphstream-project.org/doc/Tutorials/Graph-Visualisation/
You present an example of loading

LeHavre.dgs

I am wondering, does it support *.shp or *.mif?
Plus, can you send one copy of LeHavre.dgs to me for experiment? :)
Thx.
