I am going to write an alternate history timeline, and for it, I want to create legislative seating charts like this. But, I have no idea how to do this in Inkscape. Can anybody help?

I figured it out, sort of. But I have yet to create something with a pattern like the one I linked to.

You can set it up as arcs using a custom dash type. Here is how it can be done in the XML editor:

viewtopic.php?f=6&t=2400

If you first set the linetype to 10 pixels wide, curved caps then set to the dashpattern as 0, 15 (for example) you will get 10px diameter circles with 5 px spaces. You will have to play a bit with the 15 value to get it to fit the desired arc evenly for each main arc diameter.

Then convert the lines to paths and group/colour as desired.

It should be possible to automate the dashpattern part with a bit of calculation (i.e. the nearest value to 15 that divides evenly into the path length).
