{"version":"1.0","type":"rich","title":"Coronavirus Deaths Over Time With Voronoi Overlay","description":"This visualization tracks global cumulative COVID-19 deaths over time using a log-scaled line chart. Each line represents a country with over 10,000 deaths, sourced from the Johns Hopkins Coronavirus Dataset. The chart renders multiple time series as SVG paths, with a highlighted blue line for the currently hovered country. A Voronoi overlay, built with d3.Delaunay and d3-delaunay, assigns each point to a cell, enabling intuitive mouse interaction that triggers hover detection across all lines. The React-based implementation uses D3 scales, axes, and line generators.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5482b1a9cdf64ba99e839d64e1681d99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
