Here is a simple example:
To get this image, all you have to do is reference this url: http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World
You can simply couple this with python using the webbrowser library. To open the image in a web browser via python try this:
import webbrowser
url = http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World
webbrowser.open(url)
