SVG Fundamental
This example demonstrates the fundamental structure of an SVG visualization, showing how a basic HTML page can serve as a container for SVG content rendered with JavaScript. The code sets up a minimal document with a title and an empty body, preparing for SVG elements to be added dynamically. It relies on vanilla JavaScript and CSS, with no external libraries, highlighting the raw capabilities of the SVG API for building custom visualizations. The rendering approach is entirely client-side, using the DOM to insert and manipulate SVG shapes directly.
