{"version":"1.0","type":"rich","title":"Modular US State Choropleth","description":"A modular US State Choropleth maps state-level CSV data onto a continuous linear color scale, rendering each state as an SVG path using D3 v4's geoAlbersUsa projection. The example loads beerwine2.csv, which contains a normalized `value` for each state, and merges it with GeoJSON state geometries to color-code the map. Users can customize the color ramp by modifying the `lowColor` and `highColor` variables. A vertical gradient legend with an axis is included to show the value-to-color mapping. This block is a refactored version of an existing choropleth and requires a `statesdata.csv` with `state` (full name) and `value` (numeric) columns.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e985e5b291e5e3e82ddd07fff76e297c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
