{"version":"1.0","type":"rich","title":"Voronoi Overlay with Labels","description":"A multi-line chart displays cumulative COVID-19 deaths over time for multiple countries, with a logarithmic y-axis. A Voronoi overlay, built with `d3.Delaunay`, captures mouse hover events across the chart area, highlighting the nearest data point and its corresponding line. A tooltip with country name, death count, and date follows the cursor, while the active series is emphasized. Data comes from the CSSE COVID-19 time series, rendered as SVG in React using d3 scales and axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d36620ea7b74c19a6b703c533e53d02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
