This example displays a simple JavaScript console output, logging the string "hello javascript", a text constant describing "planet jupiter", and a reference to the d3 `select` function. The visualization serves as a minimal demonstration of a D3.js v7 setup within an HTML page, using a custom `bundle.js` script and the `unpkg` distribution. The page itself renders no graphical elements, showing only a static console-based interaction with imported modules and constants.
