This example approximates a bar chart using four black rectangles on a white background, each representing a data value. The bars vary in height and position, creating a static, minimalist visualization. The SVG rendering uses the `<rect>` element with explicit x, y, width, and height attributes to define each bar, laid out on a 960 by 500 canvas. The chart relies on raw SVG markup rather than a charting library or JavaScript, with the data encoded directly in the coordinates.
