This example demonstrates a minimal starter template for a D3 v3 visualization, with a simple `console.log('hello world')` statement in the accompanying JavaScript file. The page structure consists of an HTML document linking to an external stylesheet, and the visualization itself renders no graphical content. The code uses plain D3 v3 selection and utility methods, though no data binding or DOM manipulation occurs beyond the initial script execution. It serves as a clean, minimal baseline for developing more complex charts or interactive graphics.
