Can a cgi-bin program return a graphics file for an IMG tag?

I have a program which generates graphs, built on to of GD::Graph. Right now, it writes a .gif file. I'd like to modify the code and call it as a cgi-bin file so that it generates the graph as needed, without ever writing to a file. That is, I'd like to have an html page with the text 

Here's a graph:
  <IMG src=http://myHost/cgi-bin/imageGen.cgi?data=2,3&data=5,4&xlabel
+=Jan,Feb>

[download]
and have the graph appear without ever saving an image file. Can someone point me in the right direction? Thanks.
