title: How to generate graphs and charts on the fly using web2py
body: <p>I am getting data after firing from Databases. I want to generate some basic graphs using this data to interpret the results. I read some posts that <a href="http://mbostock.github.io/protovis/ex/" rel="nofollow">Protovis</a> is helpful in achieving this but i can't find much content about it. In ideal scenario I would like to use <a href="http://d3js.org/" rel="nofollow">d3js</a> generated data driven documents. </p>
