{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example presents a blank, rounded rectangle filling the entire browser window, rendered as an SVG element. It demonstrates the foundational structure of a D3.js visualization using the `d3.select` API to acquire the SVG canvas and setting its dimensions to match the viewport. The code calculates the width and height from the document body and appends a single `<rect>` element with a corner radius, offering a clean starting point for further graphical development.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c35fdf97a6042188b5550e6712de315?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
