As you can see, all contain a geographic map with a pie chart like haplogroups.

I have been researching and the best tool I can find is this:

But it seems hard to use, as it uses JavaScript, and depends on using a web browser. Is there any other more specialized or easier tool?

Have you found a solution? Given a haplogroup, how do you find our the geographic information associated with the haplogroup?

Looks you can do things like that with R (I stumbled on http://rgraphgallery.blogspot.be/2013/04/rg-plot-bar-or-pie-chart-over-world-map.html and http://stackoverflow.com/questions/20052250/pie-charts-in-ggsubplot-ggplot2, among others).
