{"version":"1.0","type":"rich","title":"usa map","description":"This example displays a choropleth-style map of US states, with each state filled by a categorical color from `d3.scaleOrdinal` and `schemeCategory10`. It uses `d3.geoPath` with a `geoAlbersUsa` projection to render the SVG paths, and the state boundaries are loaded from a TopoJSON file via `us-atlas`. Hovering a state changes its fill to yellow, while a red stroke outlines all boundaries. The code processes the TopoJSON with `topojson.feature` and appends a `<title>` element for each state name.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3cc80ec49f0e421eae807e3f5c57790c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
