{"version":"1.0","type":"rich","title":"blank canvas","description":"A full-screen rounded rectangle serves as the sole visual element, rendered as an SVG rect that dynamically fills the browser viewport based on measured client dimensions. The example demonstrates a minimal D3 v5 setup using `select` to target the SVG element and setting width and height attributes directly from `document.body` parameters.
