How do they draw charts / graphs in stackoverflow?

Question

I spent a lot of time learning VML and creating diagrams for a website once, but since VML only works in Internet Explorer, this is not very good these days.

I notice that stackoverflow has graphs on my profile page, under "reputation", but I could not see how they did it.

Can anyone suggest a way to create client charts or charts that work in all browsers? I do not want to use a server-side method in which an image file is created on the fly. I might also want to interact with the chart using JavaScript.

[Edit is not only the graphics that I want to draw. Perhaps small charts too!]

Thank.
