Let's face it: Interactive graphs and dashboards have never been easy to put together on the web. Sure, there are graphing libraries out there for PHP, but to get something that looks really good and that a user can play with has been tough. Or at least, it was yesterday.

He shows how to create a simple Flex application that takes in XML data (from whatever backend, he uses a PHP script that uses DOM) and displays the information - his sample traffic data - as a graph. This graph is an extension of the Elixir library from ILOG and makes dropping information into graphs and charts simple.

Screenshots of the Flex side of things and code for the PHP side are both provided.
