Plotrb

Vega/D3-based plotting gem for Ruby

Description

Plotrb is an experimental plotting library for the Ruby language. It brings the simplicity of Vega and the power of D3 to the Ruby science community, to allow for fast, customizable design; reusability and shareability; programmatic generation of visualizations; and improved performance and platform flexibility.

Plotrb is in many ways the child of Rubyvis (the Ruby port of Protovis). However, it improves upon Rubyvis in that it uses a DSL that will be much more familiar and natural to Ruby coders.

Plotrb was created by Wan Zuhao as part of Google's Summer of Code 2013. It is part of SciRuby.

Installation

Add this line to your application's Gemfile:

gem 'plotrb'

And then execute:

bundle

Or install it yourself as:

gem install plotrb

Usage

Currently, Plotrb is intended to generate JSON specification for Vega. If you would like to see the visualization rendered in PNG or SVG, you will have to install Vega and use its Headless Mode.

Note that Plotrb is a work in progress, so we can't guarantee that every example will work exactly.

Examples may also be found in the `examples/` directory.
