good program (preferably free) for very basic maths graphs?

Although i don't have a suggestion for your graphing program. here is something that is very similar to MSPaint, but much better.

Its called seashore and its open-source and free.

Hi, I'd like a program for my mac that I can use to do simple enough graphs, such as those for market structures in economics.

Failing that, is there an MSpaint like program for mac?

I haven't used either of these but I find appshopper to be a good source of free apps. This doesn't depend on having the latest snow leopard with the app store as most apps have ways to download them from the develper's web site if you don't use the app store to obtain them. Appshopper's search feature doesn't work that well as it brings up thousands of iOS apps for every OS X app but if you spend a little time you should be able to find several free or low cost apps to meet your needs.

BTW you do realize there are graphing capabilities in the freeware OpenOffice.org/LibreOffice, right? I often find myself opening a spreadsheet for quick calculations anyway. If you don't mind a somewhat complicated user interface, gimp is the best freeware graphics program on OS X and compares with with Photoshop CS5.

Not sure, but have you checked "Grapher"? (part of OS X).
