{"version":"1.0","type":"rich","title":"Blank Canvas!","description":"A blank, rounded rectangle fills the browser window, demonstrating a minimal D3.js setup. The visualization shows an empty SVG canvas, with no data or marks drawn. The code uses the `select` and `arc` functions from D3 v6, though the latter is not invoked. It sizes the SVG to the viewport's client width and height, then appends a single rounded `<rect>` covering the entire space. The document's body is fixed to the viewport edges via CSS, ensuring the canvas fills the screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10ef2df989734a5e8293464047a09857?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
