{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example displays a black full-screen rectangle with rounded corners on a blank SVG canvas. It uses D3 v5’s `select` method to attach to the SVG element, sets its dimensions to match the browser viewport, and appends a `rect` with an `rx` of 40 pixels. The visualization demonstrates minimal SVG rendering with a simple, static geometric shape, relying on inline JavaScript and CSS to fill the entire screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7b04dde8d2646a4b114ba12383c8e98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
