This example shows the number of airports per U.S. state, rendered as bars positioned on an Albers USA map projection. Built with the Vega-Lite API, it registers Vega and Vega-Lite, then uses a bar mark with a count transform and a projection to create the spatial layout. The visualization reads airport data from the vega-datasets package, applies custom styling from a config file, and renders to canvas with tooltips enabled.
