The diagrams package

[Tags: bsd3, library]

Diagrams is a full-featured framework and embedded domain-specific langauge for creating declarative vector graphics and animations.

This package is just a convenient wrapper around the diagrams-core, diagrams-lib and diagrams-contrib packages, so they can be installed with a single `cabal install diagrams` command.

The package also comes with flags to enable three different backends. A Haskell-native SVG backend (the diagrams-svg package) can be selected with -fsvg. This flag is enabled by default, so if you do not want the SVG backend, you must explicitly disable it with -f-svg. The SVG backend does not yet quite support all the features of the cairo backend: text alignment and embedded images are the two main missing features at this point, and of course it can only produce SVG images. It is, however, much easier to install, so it is the out-of-the-box default.

There is also a cairo backend (the diagrams-cairo package) which can be selected with the -fcairo flag. It is fully-featured and can produce PNG, PS, PDF, or SVG output; however, due to its dependencies it can be difficult to install on some platforms (notably OS X).

Finally, there is a Haskell-native postscript backend (the diagrams-postscript package) which can be selected with the -fps flag. The only feature it does not support is transparency.
