Google Chart API
Google has released a chart API that returns PNG files from an HTTP GET. The following types of charts are available:
- Line chart
- Bar chart
- Pie chart
- Venn diagram
- Scatter plot
The chart to the right was created using this URL:
http://chart.apis.google.com/chart? cht=p3& chd=s:Uf9a& chs=200x100& chl=A|B|C|D
Adding charts to Web sites just got a lot easier.

Yow! First mention I saw of this, Phil. (I'm a couple of days behind on blogposts; I jumped to your Technorati article from twitter, then caught up on you here). This looks outstanding! Very, very useful to get these kind of easy-to-use visualization tools in the cloud. Thanks for the post.

We've actually written a wrapper class for the Google Chart API if you click the link in my name.

Someone has actually already put the API to good use, if you want to see an example of an application--it's kind of dorky but pretty cool. Really illustrates the power and simplicity of the API. Also, the proprietary algorithm they use here is amazingly accurate! It's at http://lovegraph.thefootnotes.net -- worth checking out.

Hi,
I made a GUI for the API.
It's not finished yet, but I'm working on it at the moment.

Here is a PHP class to generate and cache Google Charts.
