{"version":"1.0","type":"rich","title":"PM2.5","description":"This example displays the size and structure of a PM2.5 global air pollution dataset. A large text message reports the file size in kilobytes, the number of rows, and the number of columns after loading the CSV. The code uses D3.js v5’s `d3.csv` method to fetch and parse the data from a GitHub Gist, then computes the metrics using `d3.csvFormat` and array properties. The data originates from a Kaggle dataset covering mean annual PM2.5 exposure for 240 countries from 2010 to 2017.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8de71f1581f449ddb824a1696dff952c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
