Welcome to Gruff!

Gruff is a charting library for Ruby based on RMagic or RMagick4J. Gruff generates image files which can be used separately or in web pages.

The API is mature, but we are working on improving it continuously. All contributions are welcome.

You can find many examples in the test directory along with their resulting charts in the output directory.
