Gruff is a Ruby library for generating beautiful graphs and charts as images, built on top of RMagick/ImageMagick. It supports many chart types including line, bar, pie, area, scatter, and dot charts.
Use cases
- generate charts in ruby
- create line and bar graphs from data
- render pie charts as png images
- add graphs to a rails app
- plot data series to image files
When to choose
- you need static chart images generated server-side in Ruby
- you want a simple, mature Ruby graphing gem with many chart types
When to avoid
- you need interactive browser-based charts (use a JavaScript charting library)
- you cannot install ImageMagick system dependencies
- you need SVG output
