{"version":"1.0","type":"rich","title":"country map","description":"This visualization displays a choropleth map of the United States, coloring each state in red with thin black internal borders. The map is rendered using React and D3 v5, with geographic shapes generated through `d3.geoAlbers` projection and `d3.geoPath`. State boundaries come from the US Atlas TopoJSON dataset, processed via `topojson.feature` and `topojson.mesh`. The SVG paths change to sky blue on hover using CSS, providing simple interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9a439b7ae454b61a3da20b0c9111088?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
