{"version":"1.0","type":"rich","title":"Corona Deaths Linechart with Marker Line","description":"The chart displays global cumulative COVID-19 deaths over time as a thick black line, with a red horizontal marker line fixed at 3 million deaths. Built using React and D3 v5, it renders an SVG path via `d3.line()` with time and linear scales (`scaleTime`, `scaleLinear`). The line’s y-coordinate is derived from the `deathTotal` field, which sums daily death counts from the JHU CSSE time-series CSV. The marker line’s position is computed using the same y-scale, and both elements are drawn directly in the JSX.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99b64dd11a85488f9a99c9f26a718c3e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
