{"version":"1.0","type":"rich","title":"49) Coronavirus Line Chart with 10,000 Marker Line","description":"A line chart tracks daily cumulative COVID-19 deaths worldwide, with a horizontal marker line fixed at 10,000 deaths. The React component uses `d3.scaleTime` and `d3.scaleLinear` to map dates and death totals, while `d3.line` generates the SVG path. Data comes from a JHU CSSE time-series CSV, aggregated by summing country-level deaths per day. The black stroke emphasizes the trend, and the marker line offers a fixed reference threshold.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec008af939184360b1962d67d73db3ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
