This example shows a horizontal bar chart with four bars representing categorical values A, B, C, and D, rendered as simple SVG rectangles on a white canvas. The bars are positioned using explicit x and y coordinates with fixed heights and widths, while category labels are placed to the left using SVG text elements with a shared CSS ID for styling. The visualization is built using raw SVG markup embedded directly in an HTML page, with no external libraries or JavaScript logic, demonstrating fundamental SVG layout techniques in a React-independent context.
