This example shows a minimal SVG canvas with a single gray circle positioned at coordinates (100, 100) and a radius of 100, alongside a text string exported from a separate ES6 module. The visualization uses the D3.js v5 library’s `select` and `append` methods to create the circle, while the message variable is defined but never rendered. The HTML page loads D3 from a CDN, applies a global Ubuntu font via CSS, and runs the bundled JavaScript.
