From the webpage:

Vega is a visualization grammar, a declarative format for creating, saving and sharing visualization designs.

With Vega you can describe data visualizations in a JSON format, and generate interactive views using either HTML5 Canvas or SVG.

Read the tutorial, browse the documentation, join the discussion, and explore visualizations using the web-based Vega Editor.

vega.min.js (120K)

Of interest mostly because of its use with XDATA@Kitware for example.

XDATA@Kitware Big data unlocked, with the power of the Web.

From the webpage:

XDATA@Kitware is the engineering and research effort of a DARPA XDATA visualization team consisting of expertise from Kitware, Inc., Harvard University, University of Utah, Stanford University, Georgia Tech, and KnowledgeVis, LLC. XDATA is a DARPA-funded project to develop big data analysis and visualization solutions through utilizing and expanding open-source frameworks.

We are in the process of developing the Visualization Design Environment (VDE), a powerful yet intuitive user interface that will enable rapid development of visualization solutions with no programming required, using the Vega visualization grammar. The following index of web apps, hosted on the modular and flexible Tangelo web server framework, demonstrates some of the capabilities these tools will provide to solve a wide range of big data problems.


Document Entity Relationships: Discover the network of named entities hidden within text documents

SSCI Predictive Database: Explore the progression of table partitioning in a predictive database.

Enron: Enron email visualization.

Flickr Metadata Maps: Explore the locations where millions of Flickr photos were taken

Biofabric Graph Visualization: An implementation of the Biofabric algorithm for visualizing large graphs.

SFC (Safe for c-suite) if you are there to explain them.
