{"version":"1.0","type":"rich","title":"Coronavirus Line Chart w/ 1M Marker","description":"This chart depicts the cumulative global death toll from COVID-19 over time, using data from the Johns Hopkins Coronavirus Dataset. A thin horizontal line marks the point where deaths reach one million, while a thick black path traces the rising trend. The visualization is built with React and D3 v6, using `scaleTime`, `scaleLinear`, and `line` to generate an SVG path. Data is loaded via `d3.csv` and processed by summing daily country-level death counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d587fb7b76948b09c6026eb583f231d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
