{"version":"1.0","type":"rich","title":"Fork of Coronavirus Line Chart with 1M marker line","description":"This line chart tracks global cumulative COVID-19 deaths over time, using data from the CSSE at Johns Hopkins. It plots a bold black line and overlays a horizontal marker at the 1,000,000 death threshold, plus a vertical marker at the latest date labeled “now.” Built with React and D3 v7, it uses `scaleTime`, `scaleLinear`, and the `line` generator, rendering as SVG. The `YMarkerLine` and `XMarkerLine` components draw the reference lines and labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c35a2e0c8a854f279f986a2468ebb351?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
