{"version":"1.0","type":"rich","title":"Voronoi with labels","description":"An interactive line chart displays cumulative COVID-19 death counts over time for multiple countries, using a logarithmic y-axis. A Voronoi overlay, built with `d3.Delaunay` and `d3.delaunay.voronoi`, captures mouse hover events across the entire chart area, highlighting the nearest data point and its corresponding country line while displaying a tooltip with the country name, date, and death total. The visualization uses React state for active selection, SVG for rendering, and data sourced from the CSSE COVID-19 time series dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/709764a62e9f4a8aa374c89d9995bda7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
