The Gamma: Tools for open data-driven storytelling
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 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.
The full project documentation is available on thegamma.net web site:
- Data: Providing data as a REST services discusses how to provide data for the visualization. This is just a matter of writing a simple service that evaluates queries.
- Exploring: Aggregating and visualizing data covers The Gamma scripting language and the tools that you and your readers can use to explore and visualize data.
