{"version":"1.0","type":"rich","title":"coronavirus Line Chart Practice","description":"This example shows the global cumulative death toll from COVID-19 over time as a single black line chart, with horizontal and vertical marker lines highlighting the 10,000-death threshold and the latest date. Built with React and D3 v5, it uses `d3.csv` to load time-series data from the CSSE COVID-19 dataset, `scaleTime` and `scaleLinear` for axes, and `d3.line` to generate the path. The SVG is rendered directly via React components, while `d3.axisBottom` and refs are used to draw the x-axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84fc5c2413a94a7186438cef1003c3cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
