{"version":"1.0","type":"rich","title":"Coronavirus Deaths by Country over Time (with Voronoi Hover)","description":"This example displays cumulative COVID-19 deaths per country over time using a log-scaled line chart. A Voronoi overlay, constructed with `d3.Delaunay`, enables precise hover detection across all data points, highlighting the nearest country’s line and displaying a tooltip with the death count, country name, and date. The chart uses `d3.scaleTime`, `d3.scaleLog`, and `d3.line` with React for rendering, pulling timeseries data from the Johns Hopkins COVID-19 dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f05b847ef6dd4985a7b15a5e9e81e39c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
