The Gamma: Tools for open data-driven storytelling

Build status

The Gamma logo

The Gamma is a simple JavaScript library that lets anyone create transparent and open data visualizations that are linked to the original data source and encourage the reader to further explore data and find interesting facts on their own.

The Gamma implements a scripting language with spreadsheet-inspired tooling that runs in the browser and lets users perform simple data aggregation and exploration. The package lets you run The Gamma scripts and provides a rich web-based editor that you can embed on your site.

The Gamma in action

The Gamma script

The core of The Gamma project is a simple scripting langauge that makes it easy to write code to perform data aggregation and data exploration. For example, if you want to find the top 8 athletes by the number of gold medals from Rio 2016, you can write:

olympics
  .'filter data'.'Games is'.'Rio (2016)'.then
  .'group data'.'by Athlete'.'sum Gold'.then
  .'sort data'.'by Gold descending'.then
  .'paging'.take(8)
  .'get the data'

Rich tooling is available when writing code using The Gamma web-based editor and so you get auto-completion for available operations when typing ., you can see a live preview of the transformed data and you can even modify the code using a simple user interface.

Documentation
