Update: May 13th 2015I have added a 'Download SVG' button in browsers that support SVG! Safari is not currently working, I'm not sure there's much I can do. Let me know in the comments if you run into any problems with it.
Playing Minecraft, I like making circular things. I used a chart while I was building, but wanted to be able to make variable size ovals which is something I couldn't find a decent chart of or generator capable of, so I created this!
