{"version":"1.0","type":"rich","title":"Multiple Colored Lines With Voronoi Overlay","description":"This example visualizes global COVID-19 deaths over time with multiple colored lines, one per country, on a log-scaled y-axis. Hovering near any line highlights that country’s full path in black, using a `d3.Delaunay` Voronoi overlay to capture mouse proximity. The chart is built with React and renders SVG, using `d3.scaleTime`, `d3.scaleLog`, and `d3.line` for the axis and line generation. Data comes from the CSSEGISandData COVID-19 time-series CSV, parsed with `d3.csv` and `timeParse`, showing roughly twenty countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/649aad88843a44e28deac17df804a0cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
