Please, does anybody knows if there is a grasshopper plugin or tool or instruction to graph a “spider graph”?  
a graph where you have 5 or more variables that you graph arround a point?  
of course, the graph should appear at the Rhino screen…

Thanks in advance for your time and attention

One way could be:  
Take a circle, divide it by the amount of variables. Draw lines from center to these points, evaluate the lines at the mapped parameter and connect the resulting points.

For the background divide your lines by equal numbers and connect by poly lines.
