{"version":"1.0","type":"rich","title":"Hello React!","description":"This example visualizes a choropleth map of the United States, displaying state-level unemployment rates with a green color scale derived from a TSV data file. Built with React and D3 v5, it renders state boundaries and graticules using `d3.geoPath` with an Albers projection, pulling TopoJSON data from the US Atlas. The React component hierarchy separates data loading in `useData` from map rendering in `Marks`, though the visualization currently displays a static map without completing the data-to-color binding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f849b1fc16f6489b8b4d258875a059c9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
