{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This choropleth maps crime rates per 100,000 people across U.S. states, coloring each state on a red-orange gradient from low to high values. The map uses an Albers USA projection via `d3.geoAlbersUsa()`, with state boundaries drawn through `d3.geoPath()`. State-level data from a CSV is joined to TopoJSON features from the us-atlas package, and a hover tooltip shows each state’s name and rate. A gradient legend, rendered as a Canvas image embedded in the SVG, includes an axis from `d3.axisBottom()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76c56b5af7154be0a8fde3e499abcf7d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
