I am working on a program that allows a user to input variables which are part of a huge linear equation which is then graphed. The only problem is, I have no idea how to make a graph in C#. Does anyone have a fairly simple way to do this? (Also, I have no financial resources for this project, so please don't tell me to go and buy some graphing control or whatnot.)

EDIT: I am also looking for a way to to this in HTML, JavaScript, or PHP. In fact, that would be even more helpful.

Well, you have the general idea. There's nothing built in that does graphing per se. There is the Bitmap and Graphics classes, and you can draw whatever you like with those. I believe Crystal Reports is free and will do graphs. I am certain Microsoft and others have free graphing controls as well, if you google for them. I've never needed one, so I have no specific recommendations.
