{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"This example displays global COVID-19 cumulative death totals over time as multiple line charts, one per country, on a logarithmic y-axis. Hovering over any point highlights that country’s entire line and shows a tooltip with the country name, death count, and date. The interactive hover detection uses a Voronoi overlay generated from the data points via `d3.Delaunay` and `d3.voronoi`, mapping mouse events to the nearest point. The line chart is built with React and rendered as SVG, using `d3.scaleTime`, `d3.scaleLog`, and `d3.line`, with data sourced 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/65c5c90100814a4ea448ba87d89f0e98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
