{"version":"1.0","type":"rich","title":"making a canvas!","description":"This example demonstrates how to create a full-screen interactive canvas using D3 v5 and SVG rendering. The visualization fills the browser viewport with a single rounded rectangle, responding to the window dimensions by setting the SVG width and height attributes dynamically. The code uses D3’s `select` function to target the SVG element and appends a `<rect>` element with a 40-pixel corner radius. The stylesheet ensures the body has no margins and prevents overflow, making the canvas occupy the entire display area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8bf88cdd83f04ec9b6a70132a67daf55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
