{"version":"1.0","type":"rich","title":"Fork of Country map","description":"This choropleth map colors US states by average annual sunshine hours, using a yellow-green sequential scale. The data is stored in a JavaScript Map for approximately 20 states, with missing states rendered pale green. Built with D3 v7 and topojson-client, it uses `d3.geoAlbersUsa()` for projection, `d3.geoPath()` for rendering state boundaries, and a custom tooltip on mouse events. The legend is drawn inside the SVG, and state data comes from the us-atlas states-10m GeoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cc5a25e490c4c08b197b6fd40e0d2a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
