{"version":"1.0","type":"rich","title":"Blank canvas","description":"A blank, full-viewport SVG rectangle with rounded corners fills the browser window. The visualization demonstrates the minimal setup for a Vizhub project using D3 v5, with the page dimensions retrieved from `document.body.clientWidth` and `document.body.clientHeight`. The code selects the SVG element via `d3.select`, sets its width and height attributes, and appends a single `rect` element with a 40-pixel corner radius. Styling is handled with fixed positioning and hidden overflow in the page’s CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbe963c61bda4a798c480e54c0fae9d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
