From the docstring in circles - "Note that `c` should not be a single numeric RGB or RGBA sequence because that is indistinguishable from an array of values to be colormapped. (If you insist, use `color` instead). So a slight modification of your code seems to do what you want
fig = plt.figure(figsize=(5,3))
ax = fig.gca()
xvals = np.array([0,100])
yvals = np.array([0,0])
rvals = np.array([30,10])
rgb = np.array([[255, 0, 0], [0, 255, 0]])
circles(xvals, yvals, s=rvals, color=rgb / 255.) # use color instead of c and make 0. <= rgb <= 1.

Thanks Scott! That certainly gets me closer. One question/problem I still have is that it doesn?t seem to like RGB as colors, in spite of the docs. I?ve attached a simple example.

Syrtis Major's gist at https://gist.github.com/syrte/592a062c562cd2a98a83 seems to do what you want. See this stackoverflow answer for an example of the circles function in action -

Is it possible to specify scatter plot glyph sizes - specifically, circles and, e.g., radii, in data coords, rather than ?marker size? of ?points**2??
