{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A single rounded rectangle fills the entire viewport, rendered in SVG with no data or marks. The visualization uses D3 v5’s `select` to bind the SVG element, then sets its width and height to the browser window’s client dimensions. A `rect` is appended with a 40-pixel corner radius, creating a soft-edged blank canvas. The code relies on `document.body.clientWidth` and `clientHeight` for sizing, with the body fixed and overflow hidden via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/172ac4facec84cd598ee50aa09e08adb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
