Warning: This API is deprecated. Please use the actively maintained Google Charts API instead.
While the dynamic and interactive Google Charts are actively maintained, we officially deprecated the static Google Image Charts way back in 2012. This gives us the right to turn it off without notice, although we have no plans to do so.
About the Image Charts API
This service allows you to create dynamic charts using nothing more than a URL string. To see it in action, just paste this URL into your browser's address bar: https://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World. Now try changing the text from "World" to your name.
