The line chart uses d3.scaleTime for dates, d3.scaleLinear for deaths, and d3.line to generate the path. A horizontal `line` element is positioned using the y-scale’s value for 1,000,000. Data comes from the CSSE COVID-19 time series CSV, aggregated daily across all countries, and renders as an SVG in a React component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4fe8c00608840779d6103455792cb00?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
