This example displays a static HTML page with a large, centered message reading “Hello HTML!” in bold black text, while also logging “Hello JavaScript!” to the console. The visualization uses no plotting or data libraries; instead, it relies on basic CSS styling for the message layout and a separate `script.js` file, which likely contains logic beyond the shown `console.log` call. The code demonstrates a minimal setup where HTML, CSS, and JavaScript are separated into distinct files, but no data source or rendering technique is visible beyond the text output.
