{"version":"1.0","type":"rich","title":"H1B Petition with Interactive Legend for Case Status","description":"This example visualizes H1B petition case statuses across U.S. cities on a map using React and d3.v5. The map renders state boundaries and graticules with `d3.geoPath` and `d3.geoAlbers`, while city coordinates are projected from a CSV dataset containing longitude and latitude values. An interactive legend, built as a custom React component, uses `onMouseEnter` and `onMouseOut` handlers to highlight a selected case status by fading non-matching circles. The visualization loads geographic data from the us-atlas TopoJSON CDN and petition data from a GitHub-hosted CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f145ad2030b43babbdfac5eab0dce37?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
