{"version":"1.0","type":"rich","title":"Massachusetts Crime Dataset","description":"This example displays the size and structure of the Massachusetts Crime Dataset, showing the file size in kilobytes, the number of rows, and the number of columns. It loads the CSV from a GitHub gist using D3 v5’s `d3.csv` method, which parses the data into an array of objects. The code then uses `d3.csvFormat` to re-serialize the data for size calculation and accesses the `length` and `columns` properties to count rows and fields. The resulting information is rendered into a large `<pre>` element using plain text manipulation via the Document Object Model.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a91ed0ab2d5d47ee9be5f1e0e8a6cb5c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
