What is Brunel?
Brunel defines a highly succinct and novel language that defines interactive data visualizations based on tabular data. The language is well suited for both data scientists and more aggressive business users. The system interprets the language and produces visualizations using the user's choice of existing lower-level visualization technologies typically used by application engineers such as RAVE or D3. It can operate stand-alone and integrated into Jupyter (IPython) notebooks with further integrations as well as other low-level rendering support depending on the desires of the community.
Articles and notes on Brunel can be found in the brunelvis.org blog.

Core Features of Brunel
- Supports standard charts, diagrams, maps and network graphs
- Automatically chooses good transforms, mappings, and formatting for your data
- Allows multiple combinations of visualization elements overlay bars, lines, paths, areas and text freely and in a coordinated space.
- Handles building structures for D3 diagram like hierarchies, treemaps and chords
- Handles data ranges, binning and stacking automatically
- Automatically wraps and fits text, even when animating
- Intelligently works out a good layout for the chart aspects, taking into account the data (so you don't have to guess axis sizes, for example)
- Provides flexible interactivity including tooltips, pan/zoom and interactive brushing
- Coordinates multiple visualizations in the same space, including interactive brushing
- Adds features such as Word clouds and paths with smoothly varying size
How to use Brunel
Online; no coding required
The simplest way to get started to go to the online builder application, drop in your own data or reference your data via a URL and build a custom visualization. Once you have a chart you want to share, you can:
- Just take a screenshot of the page or download the SVG to get a cool picture
- Take the HTML iframe snippet and embed it in a HTML page to have a live call to the Brunel Service
Using the code
If you want to use Brunel from Java, download the latest build and get started! You can also set up your own web server, or add Brunel to an existing one. More details can be found here.
Of course, the purpose of github is for you to grab and modify the code easily -- do that anyway you want!
If you do something cool and fun, consider contributing it back!
