**Vega-Lite** is a high-level grammar of interactive graphics. It provides a concise JSON syntax for rapidly generating visualizations to support analysis. Vega-Lite specifications can be compiled to [Vega](https://vega.github.io/vega) specifications.<commit_msg>Use examples that actually exist in the showcase. <commit_after>---
