{"version":"1.0","type":"rich","title":"Footfall","description":"This visualization reads a CSV file from a GitHub gist and displays basic metadata about the dataset as plain text in a large HTML `<pre>` element. Using D3 v7’s `d3.csvParse` and the Fetch API, it counts the number of rows, columns, and approximate file size in kilobytes. The output is then rendered into the page via `document.getElementById`, presenting a concise summary of the data’s structure without any graphical charts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f690f10e45c40c9a6ce5fa0cc135ac4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
