{"version":"1.0","type":"rich","title":"Voronoi Overlay With Labels","description":"This example shows a multi-series line chart of cumulative COVID-19 deaths per country over time. A Voronoi overlay, built with `d3.Delaunay` and `d3.voronoi`, captures mouse hover events across the SVG, highlighting the nearest data point and its corresponding country line. The chart uses a logarithmic Y-axis and a time-scaled X-axis, with a tooltip labeling the active country, death count, and date. Data comes from the CSSE COVID-19 global time-series dataset, rendered using React and D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a4cfe8a15b3453eb91acbc5424ec0b5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
