#1893 — Re: Mathematica loop question

Or this (after Patrick Scheibe):

Module[{num = 10, m = RotationMatrix[3/4 Pi], yMax},
  yMax = Last[m.{num, 1}];
  Graphics[{EdgeForm@Directive[Thin, Black],
    Table[{x, y} = m.{i, j}; {ColorData["TemperatureMap"][y/yMax],
      Disk[{x, y}, 0.4]}, {i, 0, num}, {j, 0, i}]}]]
