SVG FUNDAMENTALS
This example demonstrates how to create scalable vector graphics from scratch using only HTML, CSS, and JavaScript, with no external dependencies. It shows a minimal webpage structure where an empty body tag serves as the canvas for SVG rendering. The code relies on native browser APIs—specifically the SVG namespace and DOM manipulation methods—to construct visual elements programmatically. As a bare-bones starter template, it illustrates the fundamental building blocks for more complex data visualizations, laying the groundwork for integrating libraries like React or D3 in subsequent projects.
