Hello VizHub
A minimal D3.js example demonstrates how to render a single purple circle into an SVG canvas using d3.select and append operations. The page loads D3 v5 from a CDN, imports a local ES6 module for a message, and displays a static 50x50 pixel circle with a 25 pixel radius centered in the viewport. The visualization shows basic DOM manipulation and SVG element creation without data binding or interaction.
