This example presents a pseudo bar plot using four black rectangles of varying heights positioned on a white background. The SVG markup defines each bar with explicit x, y, width, and height attributes, creating a simple categorical comparison. The visualization is rendered directly in an HTML document using inline SVG, with the React framework imported but not utilized in the displayed code. The bars are styled with a solid dark fill, and the viewBox is set to 960 by 500 pixels.
