{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This visualization displays a blank, rounded-corner rectangle that fills the entire browser viewport, occupying the full width and height of the page’s client area. The SVG canvas is dynamically sized using `document.body.clientWidth` and `document.body.clientHeight`, with the rectangle drawn via a simple `<rect>` element appended to the SVG. The styling uses fixed positioning and hidden overflow in CSS to ensure the canvas remains edge-to-edge. Built with d3.v5, the code leverages the d3 `select` method to target the SVG element, and no data source is used, as the piece is purely a minimal geometric composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/987df6d4a13d4c6db5dd049fb363d07a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
