{"version":"1.0","type":"rich","title":"H1B Petition with Interactive Legend for Year","description":"This map visualizes H1B petition locations across the United States, with each city represented by a circle colored according to the petition year. An interactive legend on the right allows users to highlight petitions from a specific year, dimming all other circles. The visualization uses React with D3 v5 for map projection via `d3.geoPath` and `geoAlbers`, while `scaleOrdinal` maps years to colors. US state shapes come from the US-Atlas TopoJSON, and the petition data is loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f3207b91da94850ae13f53a58777a2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
