{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"A multi-line chart tracks cumulative COVID-19 deaths over time for multiple countries, with a logarithmic y-axis and interactive hovering. A Voronoi overlay computed with `d3.Delaunay` divides the chart into cells that trigger hover events, highlighting the nearest date’s data point and displaying a tooltip with the country name, death total, and date. The tooltip is rendered as SVG text, and the active country’s line is emphasized. Data comes from the CSSE COVID-19 time series, parsed via `d3.csv` and `timeParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/46b47657da6a4104bdd69ffd45061769?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
