This example demonstrates how to embed Vega-Lite visualizations in a React application. It loads the Vega, Vega-Lite, Vega-Lite API, Vega-Tooltip, and D3 v5 libraries via CDN, then uses them to render interactive charts within a single-page interface. The code creates a visualization pipeline where Vega-Lite specifications are parsed and rendered as SVG or Canvas output, with tooltips enabled for user interaction. The minimal HTML page and JavaScript setup show a practical starter template for integrating declarative visualization grammars into modern web frameworks.
