{"version":"1.0","type":"rich","title":"CSS Data Viz exercise","description":"This example demonstrates the basic usage of D3 to load and summarize a CSV dataset. It fetches a CSV file containing CSS named colors from a GitHub gist using `d3.csv`, then displays the dataset’s row count, column count, and approximate file size in kilobytes. The computed information is rendered as plain text inside a `<pre>` element with a large font size. The code relies on D3’s CSV parsing and formatting utilities, including `d3.csv`, `d3.csvFormat`, and the resulting data array’s `length` and `columns` properties.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b4653defc6943cfac4e080cbbe6018c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
