{"version":"1.0","type":"rich","title":"Covid Deaths over time with Voronoi Overlay","description":"A line chart tracks global cumulative COVID-19 deaths over time, with one gray line per country. Hovering over any point highlights that country's entire line in black. The chart uses a log-scaled y-axis and renders as SVG. A Voronoi overlay, built with `d3.Delaunay`, partitions the chart area into mouse-sensitive regions for each data point, enabling easy hover detection without precise cursor targeting. Data comes from the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University, loaded via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b85c7587cca47edb0a5ed2584df8a45?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
