Google Chart API

This is the coolest thing I've seen in a long time: Google Chart API.

The Google Chart API returns a PNG-format image in response to a URL. Several types of image can be generated: line, bar, and pie charts for example. For each image type you can specify attributes such as size, colors, and labels.

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.

Here's a chart that is generated on the fly:

And here's the URL that creates it:

=FF0000&chls=4.0,3.0,0.0&chs=200x125&chx
t=x,y&chxl=0:%7CJun%7CJuly%7CAug%7C1
:%7C%7C20%7C30%7C40%7C50&chf=bg,s,efefef

You'll find more examples here.

I wonder how difficult it would be to write VBA code that analyzes an Excel chart, and then creates a Google Chart API URL to reproduce it?
