{"version":"1.0","type":"rich","title":"Fork of Blank Canvas","description":"A full-window SVG canvas presents a single rounded rectangle on a blank page. The rectangle is sized to match the browser viewport dimensions, which are read from `document.body.clientWidth` and `document.body.clientHeight`. The code uses D3 v5's `select` to append the shape, setting its corner radius with `attr('rx', 40)`. The example demonstrates a minimal setup for creating a responsive, full-screen visual placeholder using D3 and SVG, with CSS positioning the body to fill the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4fc1f50ab7d45e89c6956996d9410b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
