{"version":"1.0","type":"rich","title":"Coronavirus Line Chart With 1M Marker","description":"A line chart tracks cumulative COVID-19 deaths worldwide over time, using data from the Johns Hopkins Coronavirus Dataset. A horizontal black marker line highlights the point where total deaths reach one million. The visualization is built with React and D3 v5, employing `scaleTime`, `scaleLinear`, and `line` to generate the SVG path, while a separate `<line>` element marks the one-million death threshold. Data is loaded via `csv` and transformed by summing daily death totals across all countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8690763f458e4a8c823312e3738d29c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
