{"version":"1.0","type":"rich","title":"Blank canvas","description":"This blank canvas demonstrates an empty SVG viewport that fills the browser window. The visualization shows a single rounded rectangle covering the entire display area, creating a blank slate. The code uses D3 v5's `select` method to target the SVG element and chain attribute setters for width and height. It retrieves the viewport dimensions from `document.body.clientHeight` and `document.body.clientWidth`, then appends the rectangle with rounded corners via the `rx` attribute, all rendered as vector graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdc2908c4a4c458c989899796e250755?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
