{"version":"1.0","type":"rich","title":"Massachusetts Chrolopleth map","description":"This choropleth map of Massachusetts displays town boundaries and highlights the town of Worcester in red, with the state’s counties distinguished by a categorical color scale. The visualization uses a React-based SVG renderer with D3’s `geoAlbers` projection, `geoPath`, and `scaleOrdinal` for color mapping. Town-to-county associations come from a CSV file loaded via `d3.csv`, while geographic boundaries are derived from a TopoJSON file parsed using `topojson.feature`. The map shows only one town colored, leaving remaining towns white.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc85a2d9f46b4438a67f0d4f58b79790?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
