I was thinking of something like this:
ListPlot[Table[n^(1/p), {p, 3}, {n, 20}], PlotMarkers -> Automatic]
But instead of the plot having perfect neat circles and triangles, the symbols would be slightly messy, and the text of the numerical labels on the axis would be in a font that looks like handwriting.
Obviously, this is not a vital need, but I thought it might be fun to do a slide presentation that looks like it is hand drawn.
Thank you.
