{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A full-window rounded rectangle rendered as a blank canvas, occupying the entire viewport with soft corners. The visualization uses D3 v5’s selection API to append a single SVG `rect` element, with dimensions bound to the browser’s client width and height via `document.body.clientWidth` and `clientHeight`. The `svg` is sized programmatically, and a CSS rule fixes the body to prevent scrolling, ensuring the rectangle remains the sole visual element. No data or interaction is present, highlighting the minimalist starting point of a blank SVG drawing surface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf9528c7747e447596ffea58dadcf8bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
