Using the Graphs

I've seen a few of the graphs pop up on blogs and message boards. I think this is great and please continue to use them, but there's one thing that you should know. The image links for the graphs on this site are not static (yet). Any time new data inserted into the database, the image file's date will change. This has to do with the our caching mechanism. So, if you want to use a graph, the only way to ensure that it will be permanent (for now) is to copy the image and host it somewhere else.
