{"version":"1.0","type":"rich","title":"Blank Canvas !","description":"A full-screen blank canvas is rendered as a single rounded rectangle filling the browser viewport. The example demonstrates minimal SVG setup with D3 v5, using `d3.select` to size the `<svg>` element to the document body’s dimensions and appending one `rect`. The code relies on `document.body.clientWidth` and `clientHeight` for sizing, while static CSS positions the body to prevent scrolling. No data or interaction is shown; the piece simply presents an empty, neutral space ready for further visualization work.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6672b64d68814990ac3e651012e1cf7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
