Is it possible to draw charts with json data?

Is there any good article that gets me started with Google Visualization API which i ll be using in my application for drawing charts with JSON data. Any suggestion.

EDIT: I was going through this question Iterating over json object for drawing a column chart?开发者_StackOverflow. This is what exactly i am trying to do? Any good ex?

Have you looked at Google's own page for the API? http://code.google.com/apis/visualization/documentation/gallery.html It has a lot of very good examples demonstrating different features.

If that's not enough, try the Chart Wizard that allows you to interactively build your chart data and then just copy the source code: http://imagecharteditor.appspot.com/ (for static image charts)

The navigation is a little confusing due to static vs. dynamic charts. Plus there are widgets, etc. But the examples and source code is there, so just look carefully around.
