5 way venn diagrams
Taking inspiration from another site on the web showing triangular based Venn diagrams for 5-data sets, I came up with a much cleaner representation:
It's not like I invented a new branch of math or anything, but hey, that's pretty darn cool. The triangle sizes are roughly proportional with the size of the datasets, which I didn't even think i could approximate, and I even like the look of it. While I knew this wouldn't be possible with circles (I had played briefly with rhomboids and triangles before), I was stuck until I saw this picture, and then realized that there was a much cleaner way to assemble the triangles using parallel edges, and tada, we had a winner.
Obviously, the more generalized version using identical sized triangles can be done as well. In inkscape, it's relatively easy make a 3 sided polygon, copy it 4 times and then rotate each one by 72 degrees and layer them with some opacity. Aren't Venn diagrams fun?
I hear the chorus calling me a geek, so I'll move on to other topics.
I'm currently planning on resuming my blogging with more frequent updates. The last month was a good break, giving me a bit more time to catch up on other things (research), but I've saved up several topics, and I'm ready to get going again. I'll try for at least 3 a week for the next while. Wish me luck.
