[Inkscape-user] multiple circles aka polor grid

Hi all,

I have been trying to make a polor grid like picture, but it's a bit hard to do it by hand every time (circle->duplicate->make smaller->duplicate->make smaller->...)

As I understand correctly [1] Inkscape doesn't have a build-in function to accomplish this, so does anyone know a workaround to speed things up a bit?

Thanks a lot! /Rick
