{"version":"1.0","type":"rich","title":"H1B Petition with Interactive Legend for Case Status","description":"An interactive choropleth map displays the geographic distribution of violent crime rates across US cities. The visualization uses a natural earth projection with graticules and state boundaries rendered via D3's `geoNaturalEarth1`, `geoPath`, and `geoGraticule` APIs. Circle markers sized by the `scaleSqrt` function represent each city's violent crime count, with data loaded from a CSV via D3's `csv` method. The map leverages React hooks for data fetching and renders all SVG elements through a component-based architecture.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f5ce2822acbc452bb14ad0d03d2e4c4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
