{"version":"1.0","type":"rich","title":"Loading and Parsing Coronavirus Data","description":"This visualization demonstrates how to load and parse the Johns Hopkins Coronavirus Dataset, displaying basic file statistics in a large preformatted text element. It fetches the global deaths time series CSV via `d3.csv`, then computes the data size in kilobytes using `d3.csvFormat`, and counts the rows and columns from the parsed array and its `data.columns` property. The final message shows the latest date column, total file size, row count, and column count, all rendered into the DOM via `textContent`. The example highlights D3’s Promise-based data loading and inspection of CSV metadata.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/46a368780b6647edaf5e8dc9ef6dbe28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
