{"version":"1.0","type":"rich","title":"Coronavirus With Voronoi Overlay and labels","description":"A line chart tracks cumulative global coronavirus deaths over time, with each country rendered as a thin gray path on a logarithmic y-axis. A Voronoi overlay, built with `d3.Delaunay`, divides the chart into pointer-sensitive cells, so hovering near any line highlights that country’s full trajectory in red and displays a tooltip with its name, death count, and date. The React component uses `useMemo` to cache the Voronoi cells, and data comes from the Johns Hopkins CSSE dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2abe15295154692a4516247d305ea3b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
