I'm trying to create a graph for sales data.

Some sales data is at the moment collected in a database we don't own.

We can only access the data through web admin to the database.

They won't be providing us any api to import the data though programming.

We can download data in cvs format through the web admin and that's as convenient as we can get.

I want to plot this data, and wonder if I could use graphite/statsd for this.  

I'm fairly new to graphite and examples I've seen so far deals with data that is happening in real time. (without the time tag which describes when events happened)
