SVG Fundamentals
This example demonstrates fundamental SVG shapes and text elements as a static bar chart-like visualization. The code uses the raw SVG API with `circle`, `rect`, and `text` tags to render four labeled rectangles of decreasing widths. The JavaScript-free page relies on hardcoded pixel coordinates and fill colors with no data binding or interaction. It serves as a minimal introduction to SVG’s coordinate system and shape primitives within a React-free HTML context.
