{"version":"1.0","type":"rich","title":"Coronavirus Basic Line Chart With 10,000 Marker Line","description":"This line chart displays the global cumulative death toll from COVID-19 over time, using data from the Johns Hopkins Coronavirus Dataset. A horizontal marker line at 10,000 deaths highlights the threshold, with a labeled “10,000” text at the left edge. The visualization is built with React and D3 v5, using `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` to generate the SVG path and axes. The marker line is drawn as a separate SVG `<line>` element, with the y-coordinate computed via the linear scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32ea712f245840f2823024f483c51fa7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
