This example shows a minimal HTML page that combines plain text with the D3.js library, serving as a bare-bones starting point for web-based visualizations. The page renders the text “Hello HTML!” using CSS for styling with a large font size and center alignment. The HTML file loads D3 v7 via a CDN script tag, while a separate JavaScript file imports a named export from another module and logs both that imported value and the D3 object to the console. This illustrates basic module import and script loading patterns without any data or visual rendering.
