{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"This line chart displays global COVID-19 death tolls over time by country using the Johns Hopkins dataset, with a logarithmic y-axis for cumulative deaths. The visualization includes hover interactivity via a Voronoi overlay: when hovering over a region, a tooltip displays the country, death count, and date, while highlighting the corresponding line. The chart is built with React and D3 v6, rendering as SVG and using `d3.Delaunay` from `d3-delaunay` for the overlay and `scaleTime`/`scaleLog` for the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0f30370577f467c8b5b0ef54ec3aa08?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
