This example demonstrates basic SVG shapes and text manipulation using D3.js. It renders a large yellow circle with a black stroke and a smaller unfilled circle on a 960×500 SVG canvas. The code imports `select` from D3 via UNPKG to set the text content of a message element to “Hello VizHub!”. It also imports a local ES6 module, `myMessage`, to provide the message string. The static SVG markup defines the circles directly in `index.html`, while the D3 selection targets a `#message` div, highlighting both DOM-based rendering and module imports.
