I plan on writing a few articles which would really be much better with images. Unfortunately, I am bad at drawing, and I hate it, anyway. I would much prefer declaring what an image should be, and letting the computer handle the actual drawing.
Diagrams is a Haskell library and domain-specific language for declaratively generating images, which would suit my purposes. I have added support for adding images to my web site based on it, and you can see me try it out on one of the pages.
Some day I will write up what I did to make this work. The code is available to inspect on GitHub.
