{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the browser window, adapting to the full viewport dimensions. The visualization is empty, showing no data or marks. It uses D3 v5's `select` to target the SVG element and sets its width and height based on `document.body.clientWidth` and `clientHeight`, then appends a single `rect` with a corner radius of 40 pixels. The page's CSS fixes the body to prevent scrolling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b01ba78caf74cf58c9d95e2c0b2a701?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
