{"version":"1.0","type":"rich","title":"Fork of Coronavirus Basic Line Chart With 10,000 Marker Line","description":"A line chart tracks cumulative global COVID-19 deaths over time, with a horizontal marker line at 10,000 deaths. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `line` generators to map dates and death totals, rendering an SVG path with a thick black stroke. The marker line is drawn as a separate SVG `<line>` element, while the React component structure (via `useData`) loads the Johns Hopkins CSSE time-series CSV, aggregating daily death sums. The X-axis is delegated to a separate component using `d3.select`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/079d72a60427459ba581233f847d5a87?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
