This example displays a simple pie chart visualization built with D3.js. The chart is rendered using SVG paths generated from data, with slices sized proportionally to their values. The code demonstrates loading D3 via UNPKG, importing the `select` function from the `d3` module, and using it to manipulate the DOM. A custom ES6 module (`myMessage.js`) provides the text content, which is set in the HTML element. The visualization is minimal, focusing on core D3 functionality and module imports rather than complex chart features.
