This example demonstrates the use of SVG vector graphics within an HTML page, rendering a simple scene with a blue background. The visualization is built using the D3.js library version 5, specifically utilizing the `d3.select` API to target the SVG element and apply styling. The code uses a fixed 960x500 pixel viewport and sets the background color through the `style` method. The project structure includes a separate CSS file that removes default margins, and a bundled JavaScript file (`bundle.js`) that contains the main logic. The SVG canvas provides the rendering surface for whatever graphics are defined in the script.
