{"version":"1.0","type":"rich","title":"Blank Canvass.js!","description":"A blank SVG canvas fills the browser window, sized to the full viewport via `document.body.clientWidth` and `document.body.clientHeight`. A single rounded rectangle with a 40-pixel corner radius is drawn across the entire space using D3 v6’s `select` and `attr` methods. The example demonstrates minimal SVG setup with D3, rendering one static shape in a fixed, overflow-hidden layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b18ea69a9d5549039ddd39be7d74860b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
