{"version":"1.0","type":"rich","title":"Loading and Parsing Life Expectancy CSV Data","description":"This example loads a World Health Organization life expectancy dataset from a GitHub gist and parses it with `d3.csv` (D3 v5). It displays the resulting dataset’s size in kilobytes, the number of data rows, and the number of columns as large text in a `<pre>` element. The code also includes commented alternatives using `fetch` with `d3.csvParse` and an async/await pattern, though only the primary `d3.csv().then()` path is active. The visualization is purely informational, summarizing the CSV’s structure without drawing charts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4b2a2aa090745cc9bb33a98ef593293?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
