R help - Sep 2014 - Parliament Seats Graph

Hi,

Is there any package (or homegrown function) that can produce
"Parliament Seats Graph"? I'm referring to the nice looking
concentric
half circles of colored "seats" as seen on Wikipedia (for example).

I can pretty easily plot the points and color them. But I can't group
the colored points in sectors, as seen on the example.

Example:

Found here (on the right, a bit down):
http://en.wikipedia.org/wiki/Verkhovna_Rada

TIA

Hi Stefan,
I can see how you would plot the points going from right to left (the easy 
way), by plotting the next point on the arc with the least increase in 
angle from the last point plotted. If this is the way you have worked out, I 
think all that you have to do is to turn the party affiliation into a factor (if
it is not already) and plot the points by the sorted numeric value of the 
factor. You will probably want to adjust the levels to some political 
dimensions before doing the sort.
