[okfn-discuss] Data for a graph on Earth

[Gael Varoquaux]

Hi there,

Still doing examples for Mayavi... This time I would like to appeal to
humanities/social sciences. I know graphs are important to these people
(we keep getting questions on the mailing list on how to build graphs),
so I was thinking of displaying a small graph on the surface of planet
Earth. For instance airline connections. The reason being that this is
some data that is not too abstract, and can talk to non-specialists.

Does anybody has an idea of a dataset that I could use for this purpose?
I had a quick look on CKAN, but to no avail. I don't need much data: the
graph can be very simple.

Cheers,

Gaël
