{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded-corner rectangle fills the viewport, rendered as an SVG element sized to match the browser window. The visualization uses D3 v5’s `select` and `arc` methods to construct a single `rect` element with no data binding or interactive behavior. The page loads D3 from a CDN, with the SVG styled via CSS to eliminate margins and prevent scrolling. This minimal example demonstrates a static canvas-like backdrop, relying solely on the `attr` method to set width, height, and corner radius of the shape.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7b4ff9187574113a2c1fd1a8b081dfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
