I was thinking about making circles around the points and then deleting the radius?!

Man, just draw circles oriented towards camera direction using points and size as input...I guess that might be over there some plugin/VB code already written to obtain the camera direction. With basic coding knowledge and Rhinocommon documentation is not very complicated to write that code.

how to delete the radius?

this wasn't a very good idea, because when the circle moves, the line stays!!!!

In Grasshopper, when you move something, you create and move a copy.

If you want to create geometry (in this case a circle and the line endpoint) from your moved point, you have to feed the original point into the move component's G input and use the point you get from the G output as input for the circle and line. The original geometry (in this case a point) will not move.

Then you right click on the components you don't want to see and deselect preview.

for example?

If we take example you constructed (from above post), then you should deselect one of the original points and it's "circle" the way Ola said:

Read the Grasshopper Primer. It will clear much of your perplexity.
