I am not sure that this is exactly statistics related question, but bear with me...

I need to graphically illustrate relations between different dance steps. Each step has two independent parameters: foot rotation in degrees and foot flexion(bending in ankle) in degrees.

So for example data would:

step a - foot r. 50, foot f. 25

step b - foot r. 34, foot f. 31

step c - foot r. -21, foot f. 0

step d - foot r. 0 , foot f.10

etc.

I thought that I could use coordinate system with x being rotation and y flexion. Is it kind of scatter plot? Maybe some other type of chart or diagram?

Also some of steps might have range of values rather then exact value like step c could have foot rotation from -21 to -5 degrees. If possible I would like to demonstrate that in my diagram. Kind of like bubble chart, just with bubble size demonstrating range rather then third variable. Maybe somekind of radar chart?

This will be used only as an illustration of how all types of steps differ just by two parameters; this is not for study or calculations.

Thanks for the help in advance.
