{"version":"1.0","type":"rich","title":"Coronavirus Line Chart With 5,000,000 Marker Line","description":"A line chart displays worldwide cumulative COVID-19 deaths over time, with a horizontal marker line highlighting the 5,000,000 death milestone. The chart uses a React component with D3’s `scaleTime`, `scaleLinear`, and `line` generator to map dates and death totals to SVG coordinates. The marker line is positioned using `yScale(5000000)`. Data comes from the CSSEGISandData COVID-19 time series CSV, aggregated by summing daily global deaths. The SVG renders the trend as a black stroke and the threshold as a thinner line, filling the browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2cfe8887621746bbaeb778c9e00d4b97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
