As I have not posted anything about FSharpChart for a while I thought I would do a quick post, one that befits Valentines Day:

Plotting the heart was surprisingly easy to do:

[ for x in -1.1 .. 0.001 .. 1.0 do
     let y1 = abs(x)+sqrt(1.0-x**2.0)
     let y2 = abs(x)-sqrt(1.0-x**2.0)
     yield (x, y1)
     yield (x, y2)]
