{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, full-viewport SVG canvas renders as a large rounded rectangle, filling the entire browser window. The visualization uses d3 v6’s `select` to target the empty `svg` element and sets its width and height to the viewport dimensions via `clientWidth` and `clientHeight`. A single `rect` is appended with a 40-pixel corner radius, creating a soft-edged frame. The CSS fixes the body position to eliminate scrolling, ensuring the canvas remains static and unobstructed, with no data or interaction yet defined.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f73b77e5085245998597fb2503bafbcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
