This example demonstrates a minimal setup for building a D3.js visualization within the VizHub framework. It loads D3 v5 from UNPKG and uses the `select` function to target a specific HTML element, setting its text content to a message imported from a local ES6 module. The page renders a centered message with large font styling defined in a separate CSS file, showcasing how to combine external libraries, local modules, and custom styles in a single project.
