{"version":"1.0","type":"rich","title":"Blank canvas","description":"A blank SVG canvas fills the browser window, with a single rounded rectangle drawn across its entire width and height. The example demonstrates the minimum setup for a D3 visualization within a React-free HTML page, using `d3.select` to target the `svg` element and dynamically set its dimensions based on `document.body.clientWidth` and `clientHeight`. The rectangle’s `rx` attribute applies rounded corners, while CSS fixes the body to prevent scrolling. This serves as a starting point for building more complex charts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34eaea46b843435ab0201111268a1c76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
