{"version":"1.0","type":"rich","title":"blank canvas","description":"A blank SVG canvas fills the browser viewport with a single rounded rectangle. The example demonstrates how to set up an SVG element to match the full client width and height. Using d3.select, the code reads `document.body.clientWidth` and `clientHeight` to size both the SVG and the `<rect>` element, which uses an `rx` attribute for rounded corners. The stylesheet fixes the body position with hidden overflow, ensuring the canvas remains stable and without scrollbars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e1e75b0718a4c94a6c2ba8d3d2585af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
