If you just want filled circles of different radii, you can do something
like this:

data = Randomu(-3L, 50) * 10
x = 0.5 > (Randomu(seed, 50) * 10) < 9.5
y = 0.5 > (Randomu(seed, 50) * 10) < 9.5
radius = cgScaleVector(data, 1.0, 4.0)
colors = Bytscl(data)
cgPlot, x, y, /Nodata
cgLoadCT, 33
FOR j=0,N_Elements(data)-1 DO BEGIN
cgOplot, x[j], y[j], SYMSIZE=radius[j], PSYM=16, COLOR=colors[j]
ENDFOR
END

Cheers,

David
