How can I plot many thousands of circles quickly?

Question

I\'m trying to plot several (many thousands) of circle objects - I don\'t have much experience working with python. I\'m interested in specifying the position, radius and color

Answer 1

scatter is probably better for you than plt.Circle though it won't make anything run faster.

for i in range(4):
    mp.scatter(xvals[i], yvals[i], s=rvals[i])

If you can deal with the circles being the same size then mp.plot(xvals[i], yvals[i], marker='o') will be more performant.

But this is probably a matplotlib limitation, rather than a language limitation. There are excellent JavaScript libraries for plotting thousands of data points efficiently (d3.js). Maybe someone here will know of one that you can call from Python.
