{"version":"1.0","type":"rich","title":"Create a new Blank Canvas with D3.js!","description":"This example creates a blank canvas by sizing an SVG to fill the browser viewport, then drawing a single rounded rectangle across the entire drawing area. The code uses D3.js v5’s `select` method to grab the `<svg>` element, sets its width and height from `document.body.clientWidth` and `document.documentElement.clientHeight`, and appends a `rect` with a 40-pixel corner radius via chained attribute setters. The SVG rendering approach is direct, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/410bb5b2746248a1b5dc2830c2a660b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
