How do I set the color of a curve with ggplotd?
Thanks.

Also see the below example on how to merge Colour with an 
existing range of points using mergeRange:

(Copied from http://blackedder.github.io/ggplotd/stat.html)

void main()
{
  /// http://blackedder.github.io/ggplotd/images/function.png
  import std.random : uniform;
  import std.typecons : Tuple;
  import ggplotd.stat : statFunction;
  import ggplotd.ggplotd : GGPlotD;
  import ggplotd.geom : geomLine, geomPoint;
  import ggplotd.aes : mergeRange;

  auto f = (double x) { return x / (1 + x); };

  auto aes = statFunction(f, 0.0, 10);
  auto gg = GGPlotD().put(geomLine(aes));

  // Generate some noisy points
  auto f2 = (double x) { return x / (1 + x) * uniform(0.75, 
1.25); };
  auto aes2 = f2.statFunction(0.0, 10, 25);

  // Show points in different colour
  auto withColour = Tuple!(string, 
"colour")("aquamarine").mergeRange(aes2);
  gg = gg.put(withColour.geomPoint);

  gg.save("function.png");
}
