{"version":"1.0","type":"rich","title":"Voronoi Overlay with labels","description":"A log-scaled line chart tracks cumulative COVID-19 deaths per country over time, sourced from the Johns Hopkins dataset. On hover, a Voronoi overlay, generated via `d3.Delaunay` from the line chart's points, captures the mouse to highlight the nearest data point and display a tooltip with the country, total deaths, and date. The active country's line is emphasized in black. The visualization, built with React and D3 v5, renders SVG elements and uses `d3.timeParse` for date handling and D3's `extent`, `max`, and `scaleLog` for scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/619554708beb45cfb2410d6729439d35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
