[...] recently had cause to use it in Brent Yorgey’s Diagrams package. It’s a lovely EDSL for creating simple diagrams, which is built on the Cairo library. The one thing it didn’t support was text — the [...]

Dougal: great! I will definitely put up a repository, just waiting for an admin to create a directory for me on code.haskell.org. I’ll be sure to let you (and anyone else who’s interested) know.

That sounds pretty neat… I can already think of something I’d like to do with it! Keep us updated if you’re going to make a repository available. I’m keen to get a look at it (and contribute if I can).

Conal: thanks! And good idea re: temporally continuous animation. If I add some built-in support for animation (I’ll probably add a bit, although that’s not really the main goal of the library) I’ll try to take that approach.

by the way, sweet library and examples!

your graphics are spatially continuous. go for temporally continuous animation. no pixels, no frame numbers. then you’ll get the same resolution-independence and scalability in time as you get in space. for example, check out FRP.

jfredett: sure. You could already do animation with it now, with not too much trouble. Since it’s an embedded DSL it’s a piece of cake to have a function which takes some sort of frame index as input and outputs an appropriate diagram, then map this function over a list of frame indices, and map renderToPng over the resulting list of diagrams. Then use some external tool to put the PNG files together into an animation. I can probably include some built-in support for this kind of thing in future versions, too.

Sweet, will it be able to do animation? It’d be nice to be able to hack up some cheap data visualization when I’m working on physics simulations or something…
