I think my randomizing of the position is throwing you off.  Here is a 
version that I think makes it more clear that the size (radius) is 
matching the color:

radius = np.arange(10)
area = np.pi*radius**2
x = radius
y = area
cmap = plt.get_cmap('spectral')
plt.scatter(x, y, s=area, c=radius, cmap=cmap)
plt.colorbar()
