{"version":"1.0","type":"rich","title":"Welcome to HTML","description":"This example displays metadata about a movie review dataset, showing the file size, row count, and column count in a styled text container. The page loads a CSV file from a GitHub gist using `d3.csv`, then calculates the file size with `d3.csvFormat` and presents the information in a `<pre>` element. The visualization uses a custom background image via CSS, with text styled through `myStyles.css`, and includes D3 v7 imported from a CDN. The data source is a customer dataset fetched from an external URL.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74778c862a7343918b5aa1b43c441e7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
