This image was copied from wikipedia:en. The original description was:
The cycloid as brachistochrone.
Cycloid created with gnuplot using the commands
set terminal eps color set output "brachistochrone.eps" set nokey set noborder set noxtics set noytics set size ratio -1 set parametric plot [t=0:5] t-sin(t), cos(t)-1 with lines lw 5
Then touched up with inkscape and exported as png. (Creating png output from gnuplot is bad since then the curve won't be properly anti-aliased.)
