This example presents a minimal stacked bar chart scaffold using D3.js v5. It demonstrates how to load D3 from a CDN via UNPKG, import API functions like `select`, and import local ES6 modules. The code sets the text content of a `div` element to display the message “Hello VizHub!”, highlighting the basic integration of D3 selections with modular JavaScript. The chart itself is not rendered, as the focus is on setup and module usage.
