{"version":"1.0","type":"rich","title":"Coronavirus Basic Line Chart With 10,000 Marker Line","description":"This chart shows the total number of COVID-19 deaths over time as a single black line, with a horizontal reference line marking the 10,000-death threshold and a label for that value. Built with React and D3 v5, the code uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` to generate the path, and `d3.extent`, `d3.max`, and `d3.csv` to fetch and parse the Johns Hopkins time-series dataset. The SVG rendering uses a `<path>` element for the line and a `<line>` for the marker, with styling applied through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dd237f5e66c485690766a7682fc10a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
