{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example presents a blank, rounded-rectangle canvas that fully fills the browser viewport. It demonstrates a minimal setup for a D3.js visualization using the `d3.select` API to target the SVG element and set its dimensions based on the document's client width and height. The code then appends a single `rect` element with rounded corners (`rx` attribute), whose size matches the viewport. The visualization is rendered as a static SVG using D3 v5, with CSS positioning that fixes the body to the screen edges and hides overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e77c6b4345e5425fa37ef1ef44f322f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
