{"version":"1.0","type":"rich","title":"Loading and Parsing CSV Data","description":"This example demonstrates how to load and parse three CSV datasets from GitHub Gists using D3 v5. It displays the file size in kilobytes, row count, and column count for each dataset—PM2.5 air quality data, bike rental records, and COVID-19 infection statistics—inside a styled `<pre>` element. The code uses the `d3.csv` method to fetch and parse each file, then `d3.csvFormat` to calculate the raw data size, and `data.length` and `data.columns.length` to report the dimensions. Results are appended incrementally as each promise resolves, with the final output rendered to the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9a5519b287a438794aa3d79db524103?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
