I would like to plot a bubble diagram, where each data point has three numbers; x,y and a size (the radius of the bubbles).

Despite extensive search on the Internet I have not come across any example in julia.

Thanks

For Gadfly, use the `size` aesthetic:

```julia
coord = Coord.cartesian(xmin=0, xmax=1, ymin=0, ymax=1)
p = plot(x=rand(100), y=rand(100), size=rand(1:8, 100)./150, Geom.point, coord)

```

Note the status of a [sizekey](http://gadflyjl.org/dev/tutorial/#Continuous-Scales-1) is to be done.

You can use [`scatter` in PyPlot](https://matplotlib.org/api/_as_gen/matplotlib.pyplot.scatter.html#matplotlib.pyplot.scatter): `scatter(x,y, s=radii)`

Thank you! Scatterplot that was what I was looking for.
