You could use ImageMagick to create an image of the output you want. I've always found it pretty straightforward.

If you wish the client side to render this I recommend using the canvas tag See reference here: http://www.html5canvastutorials.com/tutorials/html5-canvas-bezier-curves/

Or use imagemagick backend if you with the server side to do it

look up Bezier Primitive on page http://www.imagemagick.org/Usage/draw/#bezier
