{"version":"1.0","type":"rich","title":"Loading and Parsing Coronavirus Data","description":"This example demonstrates loading a global COVID-19 death time-series dataset using D3 v5. It fetches a CSV file from the Johns Hopkins CSSE GitHub repository and parses it with `d3.csv`. The visualization displays a large-text summary showing the data’s size in kilobytes, the number of rows, and the number of columns, computed via `d3.csvFormat` and the parsed array’s properties. It relies on the native `fetch` API and a promise handler, with commented alternatives using `async`/`await` and nested callbacks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54c5fb0a156148819c29425eac9db27e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
