{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, interactive canvas fills the browser window, rendered as a single rounded rectangle sized to the full viewport. The visualization demonstrates a minimal SVG setup using D3 v5, where the `select` function targets the empty `<svg>` element and dynamically sets its width and height attributes based on `document.body.clientWidth` and `clientHeight`. A single `<rect>` is appended and styled with a corner radius of 40 pixels. No data is loaded or transformed; the piece exists purely as a static starting point for further layering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b7ae2b6b3c0414e8c8643a7c802ec09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
