{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"A line chart displays global coronavirus deaths over time for multiple countries on a logarithmic y-scale, with a Voronoi overlay enabling mouse-based highlighting of the nearest data point and its corresponding country line. The chart uses React with D3 v5 scales and line generators, while the overlay leverages `d3.Delaunay` and `d3.voronoi` to compute cell regions for hover detection. Data comes from the Johns Hopkins Coronavirus dataset, rendered as SVG paths with axes and gridlines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2dddcca49b214460a59575af25a1b6d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
