{"version":"1.0","type":"rich","title":"A9 US Choropleth Map","description":"This example shows a choropleth map of U.S. state poverty rates using 2023 data from Poverty2023.csv. The map colors each state with a sequential red scale based on the percentage of the population living below the poverty line, with missing data rendered in gray. Hovering over a state displays a tooltip with the state name and its poverty rate. The visualization uses D3 v7’s `d3.geoPath` with the `geoAlbersUsa` projection to render state boundaries from TopoJSON, and `d3.scaleSequential` with `d3.interpolateReds` for color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a0f985417a8f4b5cb0d7fa67702dbd04?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
