I especially like the time series mode where flot assigns very meaningful time labels on the x axis when you zoom in and out. (based on unix timestamps * 1000, so easy to retrieve from a database) You can load data from python quite easily using an jquery ajax call and json.dumps() in the view on the server side. In general it surprises me how well the client side graph libraries scale if you load a lot of data into them.
