vega-lite-api

The API uses method chaining like vl.markBar().data().encode(), making code readable and maintainable, as demonstrated in the README example generating Vega-Lite JSON from JavaScript.

It works uniformly in browsers, Node.js, and Observable notebooks, with detailed setup instructions provided for each environment in the README.

Seamlessly accesses all Vega-Lite features, such as tooltips and type-safe encoding, evidenced by examples using vl.tooltip() and field-specific methods like fieldQ().

Enables data-driven chart generation through JavaScript, allowing for dynamic updates and reuse, unlike static JSON specifications.
