How well does plot.ly do with plain old equation plotting? In particular, I'm looking for something that can produce mobile friendly plots that scales diagrams automatically to show relevant features (x, y intercepts, inflection points, etc) for simple function families - y= mx + b, ax^2 + bx + c, etc.

Any suggestions on available libraries, or am I better to start from scratch on this?

Check out JSXGraph:

It's mobile friendly so long as the user's browser supports canvas (in my experience with it). It supports multi-touch devices too, but I haven't verified that.

You could compute a few [x,y] values for an equation y=f(x) and plot them using any line chart plotting library

Well, yes, that was the question! Got any favorite line chart plotters?
