Vega-Lite

JSON grammar for statistical graphics

About

Vega-Lite is a high-level grammar of interactive graphics. It provides a concise, declarative JSON syntax to create an expressive range of visualizations for data analysis and presentation.

Compared to Vega , Vega-Lite provides a more concise and convenient form to author common visualizations. As Vega-Lite can compile its specifications to Vega specifications, users may use Vega-Lite as the primary visualization tool and, if needed, transition to use the lower-level Vega for advanced use cases.

Check out the documentation and take a look at our example gallery . Follow us on Bluesky to stay informed about updates.

With Vega-Lite, we can start with a bar chart of the average monthly precipitation in Seattle, overlay a rule for the overall yearly average , and have it represent an interactive moving average for a dragged region . Next step
