title: How to graph mysql data in python?
body: <p>Let's say I get sales data every 15 minutes. The sales transactions are stored in a mysql database. I need to be able to graph this data, and allow the user to re-size the scale of time. The info would be graphed on a django website. </p>
  
  <p>How would I go about doing this, and are there any open source tools that I could look into?</p>
