Displaying graphs/charts in Django

Question

I'm making a report app in Django that involves plenty of graphs and charts.

Is there an easy graphing library/module that allows me to achieve this workflow:

1. Execute my SQL queries
2. Parse the returned data to the graphing library/module
3. Graphing library/module manipulates the data into a chart/graph which I can output to a Django template easily.

I've spent the last couple of days playing around with Matplotlib and Django. There are seemingly only a few ways to get the graphs to render in Django.

1. Use 2 views, one to render the PNG and the other one to output the HTML with the img src pointing to the first view. Link
2. Data URI's
3. Write the image to file and then call it with the view

Is there anyway I can do this more easily?

Thanks
