Fooplot is neat!
I think this is pretty neat. The fooplot.com/yourfunctionhere is cool.
I couldn't plot a circle though, it only plotted a semi-circle. Same with a parabola.
I would love to see the following features:
- Plot for y = constant, x = constant
- Chart Save-as
- Support multiple plots using the fooplot.com/yourfunctionhere URL. Currently it supports only one equation.
- Upload XML data.
