This example displays a map of US states, each rendered as a path with a distinct color from a categorical scale. It shows how each state can be uniquely identified and visually separated using a color-coding scheme. The visualization uses D3.js version 5, specifically the `d3.geoPath` and `geoAlbersUsa` projection to draw the map, along with `scaleOrdinal` and `schemeCategory10` for coloring. It loads US state boundaries from the us-atlas 10m TopoJSON dataset and creates SVG paths with hover effects defined in CSS.
