This example displays the text “Hello VizHub!” centered on a dark gray background. The message is rendered in a large, light gray Ubuntu font. The code uses D3.js (version 5.5.0) to select the HTML element with the ID `message` and set its text content to a string imported from a separate module. The styling is applied via an external stylesheet that configures the page’s background, text alignment, color, font size, and font family, importing the Google Fonts stylesheet for Ubuntu.
