You need to write some Maths to calculate when "two lines could intersect" and then draw a circle with a small at that point to highlight the cross-cutting.

Without code, there is hardly anything we can do.

You can also use coding, there is no problem using the code.
But how to draw the number of customization lines and create events for each of the points?

The WPF Canvas control is what you should be focusing on.
