{"version":"1.0","type":"rich","title":"H1B Petition with Interactive Legend for Year","description":"A choropleth map displays H1B petition locations across the United States, with each city’s year color-coded using a categorical ordinal scale from d3’s `schemeYlGnBu`. An interactive legend, built with React components, allows hovering to filter and highlight petitions from a specific year while dimming others via opacity. The map uses `d3.geoPath` with a `geoAlbers` projection and US-Atlas TopoJSON data, while city coordinates are loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f859daffcc04d1ba201f8c5778db78a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
