{"version":"1.0","type":"rich","title":"Coronavirus Line Chart with 10,000 Marker Line","description":"A line chart shows the global cumulative death toll from COVID-19 over time, with a horizontal marker line highlighting the threshold of 10,000 deaths. The chart uses D3 v5's `scaleTime`, `scaleLinear`, and `line` to generate the path, while React renders the SVG. The X axis maps dates parsed with `timeParse`, and the Y axis deaths from the CSSE global time-series CSV. Styling uses black strokes, with the marker line drawn as a separate SVG `<line>` element. The visualization waits for the remote data to load before drawing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e3c9a56f09e4efa97aa9c95b34ce33f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
