Is there a way to show a 3-D surface plot in the browser?

I've got a bunch of data for 3-D surface plots. I want to build a quick web interface to let me browse through that data. Are there any (free) packages out there that can easily show surface plots? I found this question but the suggested libraries did not support surface plots.

If it requires a plugin like flash / java that开发者_如何学C is fine. This is for prototyping so a quick 'n dirty solution is preferred.

Right now, the only option I have come up with is to use gnuplot to serve up static images. It would be awesome if there was some way to provide an interactive 3-D surface plot in the browser.

Very recent versions of gnuplot seem to do exactly what you want: HTML 5 canvas demo.

Why not just use a java applet? If you're using java you can use jogl (open gl library) which gives you 3D rendering.
