This example demonstrates a blank SVG canvas of 200 by 200 pixels, created within a `div` element. The visualization relies on a single D3.js method, `d3.select('#circle')`, to target the container and `.append('svg')` to add the scalable vector graphics element. The SVG dimensions are set explicitly using `.attr('width', 200)` and `.attr('height', 200)`, producing an empty drawing space. The page is structured with a linked external stylesheet and loads D3 version 6 from a CDN, making it a minimal starting point for further graphical additions.
