How can I change the color and thickness of a connector line?

From the Format --> Line menu

I know how to do that. I want to do it automatically. I am creating a
flow and certain line colors mean different things. If they select a
type of line, I want to change the color of it after it is placed.

I figured it out:

Visio.Shape line = VisPage.DrawLine(x1Pos, y1Pos, x2Pos, y2Pos);
celobj = line.get_Cells("LineColor");
celobj.Formula = "3";
