{"version":"1.0","type":"rich","title":"Loading and Parsing Coronavirus Data","description":"This example demonstrates the raw size and structure of the Johns Hopkins Coronavirus Dataset by displaying three key metrics: file size in kilobytes, row count, and column count. It loads the global deaths time-series CSV and parses it using `d3.csv`, then reports the number of columns from the dataset’s header. The code computes the file size from `d3.csvFormat(data).length` and renders the results as large text in a `<pre>` element via `textContent`. It uses D3 v5’s promise-based loading API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fb62b8e305a431ebbe3792083b48644?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
