This example demonstrates how to build interactive visualizations from the ground up using SVG fundamentals. It shows the process of creating and manipulating basic SVG shapes, with code examples for rendering circles, rectangles, and paths. The implementation relies on the SVG API for drawing primitives and uses JavaScript DOM methods to dynamically generate elements. The example serves as a self-contained reference, with the source code contained in a single `index.js` file that outputs a blank HTML document as its starting point.
