This example presents a simple bar chart constructed entirely with SVG `<rect>` elements rather than a charting library. Four black bars of varying heights sit on a white background, with the values encoded by each rectangle’s `y` and `height` attributes. The chart uses raw SVG markup inside an `index.html` file, with no JavaScript or data binding—the bars are hardcoded. The visualization demonstrates how basic geometric shapes can approximate a bar chart without relying on D3 or other plotting tools.
