This example displays a simple webpage layout built with HTML and CSS, featuring a header, navigation tabs, two main body images, and a footer with additional links. The page uses D3.js v5, specifically importing the `select` function from the D3 module to set the text of a message div, which shows a message from a local module. The styling uses an external stylesheet with embedded Google Fonts (Ubuntu) and CSS properties for layout, colors, and hover effects on the navigation and footer links.
