{"version":"1.0","type":"rich","title":"Multi-Line Voronoi","description":"This multi-line chart displays monthly unemployment rates for U.S. metropolitan areas using an invisible Voronoi tessellation to improve mouseover interaction. The closest point to the cursor on any line is automatically highlighted, with a focus circle and label showing the city and its value. Users can toggle the Voronoi overlay visibility via a checkbox in the top-right corner. The visualization is implemented with D3 v4, renders to SVG, and supports hover-based exploration of unemployment trends across many cities simultaneously.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e4e7af8e140d693da724b66170c8012d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
