I'd like to say I obviously knew my wind graph idea wasn't new, but honestly I hadn't thought about it. It was an interesting gadget I wanted to make. However, it was either standard or simple enough that, after I mentioned it, Revar (of Fuzzball MUCK fame) added one to the Belfry.com weather page's graph section. Now I know it's called a wind rose graph, at least..
And after grabbing Revar's data, my code seems to outright not work anymore. Yay me. I don't feel like it's worth bothering to finish if it's not so apparently undone a problem, but then, that's admitting I thought it was something novel when I should've known better.
