{"version":"1.0","type":"rich","title":"Coronavirus Line Chart With 5,000,000 Marker Line","description":"A coronavirus line chart tracks cumulative global deaths over time, with a horizontal marker line highlighting the 5,000,000-death threshold. The SVG visualization uses React to render a black path generated by d3.line, scaled with d3.scaleTime and d3.scaleLinear. Data comes from the CSSE COVID-19 time series CSV, aggregated daily via d3.csv and timeParse. The marker line is explicitly positioned using the y-scale’s output for 5,000,000, emphasizing the milestone against the full death-total trajectory.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28dd85657b3a4e178d71800141554c59?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
