This example demonstrates fundamental SVG rendering techniques using D3 v3, with a blank HTML page and a JavaScript file that logs “hello world” to the console. It includes minimal styling through CSS, where a message class is defined with a large 12em font size and centered text alignment. The visualization serves as a basic scaffold, showing how an SVG container, D3 selections, and CSS styling are prepared for custom chart development. No actual data or geometric shapes are drawn yet.
