{"version":"1.0","type":"rich","title":"Loading and Parsing Coronavirus Data","description":"This example demonstrates how to load and parse the John Hopkins Coronavirus dataset. It uses the `d3.csv` API to fetch the CSV file, then calculates and displays the dataset's size in kilobytes, row count, and column count. The final message is rendered in a large `pre` element. The code also includes commented-out alternatives using `fetch` with async/await and nested promises, but the active implementation relies on D3's built-in parsing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9d41b5e2f434b538c2dfca0c631e638?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
