This example demonstrates how to integrate D3.js with ES6 modules in a minimal VizHub setup. It shows a simple text message rendered in a large, centered font, using D3’s `select` function to update the DOM content. The code imports `select` from the d3 library and a custom `message` export from a local module, while loading d3.v5 via UNPKG. The visual output is static, with no interactive behavior or data-driven rendering.
