{"version":"1.0","type":"rich","title":"Medical Cost Data","description":"This example summarizes a medical cost dataset loaded from a CSV file, displaying its size in kilobytes, row count, and column count in a large text element. It uses D3 v5’s `d3.csv` to fetch and parse the data, then `d3.csvFormat` to measure the data size. The code also includes commented-out alternatives using `fetch` with `async/await` and a nested promise chain to illustrate different loading patterns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7330ca48554e4beba7afaf88cc45d120?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
