There are a bunch of ways to do this. One way is to pregenerate the 
charts you need and store them as .png or .gif files on the server. If 
you need truly dynamic images, then you need to make a Python program 
(WSGI, CGI, whatever) that returns the image/png on the fly. It's not 
easy to do this with matplotlib, but it's not too hard; search the 
mailing list archives for notes about getting the image bits in memory 
rather than drawing on screen or writing to disk.

All depends on your load and expectations. If the 1 second is all CPU 
time, then 1 second means you can only generate 100,000 or so graphs a 
day per server.
