SVG fundamentals
This example demonstrates the SVG fundamentals of creating and styling basic shapes. It generates 100 rectangular elements, each positioned 20 pixels apart with a 10-pixel width, creating a striped pattern across the canvas. The code uses the Document Object Model’s `createElementNS` method to construct SVG nodes and sets attributes like `x`, `width`, and `height` directly. The visualization uses no external libraries, relying instead on native browser APIs to build a static grid pattern from repetitive geometric primitives.
