Vega-Lite for Looker

Vega is an incredible way to create visualizations, stated in their own words:

Vega is a visualization grammar, a declarative language for creating, saving, and sharing interactive visualization designs. With Vega, you can describe the visual appearance and interactive behavior of a visualization in a JSON format, and generate web-based views using Canvas or SVG.

This Looker version adds a number of ui elements to craft visualizations in Vega-Lite, a higher-level language built on top of Vega:
