{"version":"1.0","type":"rich","title":"Coronavirus Deaths Over Time by Country With Voronoi Overlay","description":"A line chart displays cumulative COVID-19 deaths over time, with a gray line for each country from the Johns Hopkins dataset. A Voronoi overlay, built with `d3.Delaunay`, enables hover interaction: moving the mouse over any point highlights the corresponding country’s full line in black and shows a tooltip with its name, death count, and date. The SVG chart uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` for axes and paths, with React handling state updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fd967e8d33e4144971efa0fc8065b63?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
