d3 export demo

This is a proof-of-concept demo for saving d3js graphics as PDF/PNG/SVG files.

Objective

CGI takes incoming SVG serialization. Use graphics toolkit to open SVG serialization as input, output PNG or PDF as output.

This perl implementation just performs a system call on rsvg-convert, nothing specific to perl.

Options

• librsvg
• imagemagick http://stackoverflow.com/questions/15119679/converting-an-svg-with-imagemagick
• batik

See http://stackoverflow.com/questions/4809194/convert-svg-image-to-png-with-php for another nice overview. We just run rsvg-convert man rsvg
