Thank you, I'll be making some tweaks after I merge this in because I think relying on the logic that 3 coordinates always = circle is kinda flawed because it can potentially be a triangle polygon, so I'll be adding a "shape" attribute to the image map, I will tag you in the new PR.

I believe a triangle poly would be six numbers, each cord is an x,y. the circle being just 3 numbers is due to x,y,radius but it does future proof the implementation
