.Net Magazine:
Create an SVG data visualization with PHP
Sep 13, 2011 @ 12:13:25

On the .net magazine site (yes, really) there's a recent post from Brian Suda about creating SVG images with PHP thanks to the GD functionality that's included in every release.

If you’re working online, then canvas springs to mind. It allows you to draw raster graphics quickly and easily. If you want, there are also plenty of image code libraries that can generate GIFs, JPEGs and PNGs on request. But what if your target isn't always online? What if you’re aiming for print? Then you could use a raster graphic, but it would need to be pretty large. A better solution is to create a vector-based image format from your code. This is where SVG (Scalable Vector Graphics) steps in.

He starts by explaining a bit about SVG and what it is for those that haven't worked with it before. He givesn an example of a poster from Wired showing circles with colors from their covers over the last 15 years. He shows how to do something similar with images of the .net magazine covers, pulling out the color frequency with the imagecolorat function. Toss in a bit of markup and some formatting of the color output and you'll get circles with concentric rings with the most prominent colors ending up the largest. You can see his result here.
