{"version":"1.0","type":"rich","title":"Blank Canvas!","description":"A black rounded rectangle fills the entire browser window, creating a stark, minimalist blank canvas. The visualization uses D3 v5’s `select` method to target the SVG element, then sets its width and height to match the viewport dimensions. It appends a single `rect` with rounded corners (`rx`) and a black fill via CSS. The code dynamically reads `document.body.clientWidth` and `clientHeight` to size the graphic responsively, demonstrating a simple SVG rendering approach with no data or interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fb518014057a49548eb9debad1357deb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
