{"version":"1.0","type":"rich","title":"Line Chart With Voronoi Overlay With Labels","description":"This chart displays cumulative COVID-19 deaths over time for multiple countries, using a line chart where hovering over any point highlights the corresponding country's entire trajectory and displays a tooltip with the country name, death count, and date. The implementation uses React with D3 v7 scales, line generators, and axes, while a Voronoi overlay built with `d3.Delaunay` captures mouse events across the entire plot area for precise hover detection. Data comes from the CSSEGISandData COVID-19 time series dataset, with the active line emphasized in black and labeled via SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fc3f5579aad24c0d84acf8605a099d1b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
