It is very simple task to make such map of points, but can you explain more what do you exactly mean by attack system?
For example do you want a simple page that each point would be removed by clicking on that?
I can make the algorithm uniform, random, filling points for any accuracy.
Give me an example radius of the circle, and the precision of the coordinates X, Y.
Or I'll do on the basis of the values of chosen me.
Let me know.
