{"version":"1.0","type":"rich","title":"Massachusettts Drop Out Rates","description":"This example displays a text-based summary of longitudinal dropout rates by district in Massachusetts, sourced from public MA DESE data. It shows the total file size in kilobytes, the number of data rows, and the number of columns parsed from the CSV. Using D3 v5, the program loads the remote CSV via `d3.csv`, then formats the data with `d3.csvFormat` to compute byte length and accesses the parsed rows and columns properties. The result is rendered as plain text inside an HTML `<pre>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/331f9e6a5b6d42308905de45a0990d6c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
