Hi, once I cleaned up my scripts and rewrite some parts for easier use
it could be very well automated. So in general the answer would be: it
can be done ;-)

Here's a very quick (simplistic) summary:
1. I've downloaded free availably so called "shapefiles" which contain
country-shapes (multiple polygons) composed of coordinates (lat,lon). 
2. wrote some perl scripts to read these files out with the help of some
already available modules  and generated and generated some out of it
for easier use.
3. with the help of the GD module  I plotted these coordinates and
voila, here is the world map.
4. now I only need some input data, like tor average user data and some
other stuff like internet population per country data (from the world
fact book..the cia one).

Another question was:

Yes, right now it just shows color data without the scale data/numbers.
I will think of a better way to display this.
Anyway, these graphs were more like a side effect of my map plotting
experiments and i found them interesting. If time allows I will try to
enhance and automated them.
..till then, happy tor surfing/networking/relaying/developing..
