{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"A multi-line chart displays cumulative COVID-19 deaths over time for the US, Italy, and France, using a log-scaled y-axis. A Voronoi overlay, built with `d3.Delaunay` and `voronoi.renderCell`, captures mouse hovers to highlight the nearest data point and its line, while a tooltip shows the country, death count, and date. The visualization is rendered in SVG within a React component, updated via `useMemo` and React state, with data loaded from the CSSEGISandData COVID-19 time-series CSV.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53992e3a206b4562be3407b6e9ee38c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
