vega-lite

Vega-Lite is a high-level grammar of interactive graphics that enables users to create complex, multi-view visualizations by declaring data mappings and interactions in concise JSON specifications. It is designed for data scientists, analysts, and developers who want rapid, declarative charting without deep programming, while automatically generating optimized Vega specifications. Its interest lies in balancing expressive power with simplicity, allowing rich interactivity (e.g., brushing, linking) and composition from a minimal, readable syntax.
