{"version":"1.0","type":"rich","title":"Welcome to HTML","description":"This example displays a webpage titled \"This page displays customers\" with a centered heading and a message area that summarizes a customer dataset. It fetches the data from a CSV file hosted as a GitHub gist using the `d3.csv` method, then reports the dataset's size in kilobytes, row count, and column count via `d3.csvFormat` and the `data.columns.length` property. The page uses a customer SVG as a background image via CSS, while the JavaScript dynamically writes the metadata into the `<pre>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6269d2df19434701a40c515ff23c3b6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
