This example demonstrates a bubble map of the United States, using bubble size to represent data values for selected states. It leverages the Highcharts library, specifically the `Highcharts.mapChart` method with the `mapbubble` series type, alongside the `highcharts.js` and `maps.js` modules. The map uses the built-in US state GeoJSON data from Highcharts’ map collection, joining state codes like `US-CA` to display proportional bubbles. The code includes hardcoded data for states such as California and Texas, with sizing controlled by `minSize` and `maxSize`.
