I would like to display multiple colors (and potentially shapes and sizes) of data points in a Google Chart scatter chart. Does anyone have an example of how to do so?

I answered my own question after waiting SECONDS for an answer here :-)
You can indeed have different colors for different data elements. For example:
It's the chm= that does the magic. I was trying to have multiple chm= statements. You need to have just one, but with multiple descriptions separated by vertical bars.

Awesome, Thanks! I would not have thought of using the chm that way. – davethegr8 Sep 16 '08 at 21:48
You can only use one dataset in a scatter plot, thus only one color.

From the API description:
Scatter plots use multiple data sets differently than other chart types. You can only show one data set in a scatter plot.

You could effectively fake a multi-color scatter plot by using a line plot with white lines and colored shape markers at the points you want to display.

Here's another example: twitter charts. I'm hoping to do the same thing. Need to find out how to do the concentric circles.
