I don't know of any websites, however I can recommend some free software for Windows that I have used for simple drawings. Paint.Net is a good one. I have used it for drawings and figures for my classes. The learning curve is very shallow.

Gimp comes highly recommended, but I don't know if there is a windows version (never used it)

Graphs, well, I use excel on my desktop and openoffice.org on my laptop. I have done basic graphs with both of those.

Hope this helps.

Your request in is in a math discussion forum and not very specific with regard to the requirements, so ... tikz (http://sourceforge.net/projects/pgf/). A LaTeX package to make wonderful graphics.
