The chart above is provided via data added within the following URL using a new service from GOOG:
http://chart.apis.google.com/chart?cht=p3&chd=s:Z1a&chs=300×100&chl=Booth%20Babes|Science|Computers
This is GOOG’s Chart API at work that lets you dynamically generate charts. You can pass in optional parameters for color, legend, chart type, range markers and more. So far it supports these basic chart types: Line, Scatter, Bar, Venn and Pie.
The Google Chart API returns a PNG-format image in response to a URL. You can include a Chart API image in a webpage by embedding a URL within an <img> tag. When the webpage is displayed in a browser the Chart API renders the image within the page.
The encoding methods are pretty straightforward and you can learn how to leverage this yourself for your own web site from GOOG’s Chart Dev Guide.
Here’s some more examples, all generated by URLs, not by linking to a graphic, there are many more possibilities with this service, i’m already coming up with a To Do list of stuff for Geeknews to leverage this…:
