{"version":"1.0","type":"rich","title":"coronavirus line chart","description":"This visualization displays the total number of coronavirus deaths worldwide as a single numeric readout, updated to the dataset’s most recent date column. It uses React with a custom `useData` hook that loads the Johns Hopkins CSSE time-series CSV via `d3.csv`, then sums the last column’s values across all countries. The total is formatted with `d3.format` (the `format(\",\")` comma formatter) and rendered inside a React component. While called a “line chart,” the code only presents the cumulative death toll as a message, not an actual line graph.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cee9458ecce1473882667b224c37e71d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
