To expand a bit (as a TikZ user and a former METAPOST user): METAPOST is older, has (I think) less add-ons than TikZ, but has a few very distinctive features, most notably drawing "nice" Bezier curves without specifying the control points, and a declarative engine for solving systems of linear equations - a very nice thing to have when you want to find intersections of lines. (TikZ has the former if you use LuaTeX and some package I don't remember the name of, and the latter sort-of, i.e., much less general.) METAPOST is rather sparsely documented (that said, I used it for considerable time and was satisfied with it). If you stick with METAPOST, consider looking at ConTeXt, which heavily extends it with the so-called "METAFUN macros". Most probably, you want TikZ. Excellent software, excellent documentation, numerous add-ons. Nice things are: - it has a _lot_ of ways to specify coordinates (2D, pseudo-3D, polar coordinates and a lot more), - there are a lot of ways to add various labels (called "nodes") to the drawing.
