A black-and-white bar chart displays four labeled categories, A through D, as horizontal bars positioned against a white background. The visualization uses SVG rectangles to draw each bar, with the width of each rectangle representing its value, and text elements for labels. The bars are arranged in descending order of width, offering a clear visual comparison of the dataset. The code uses plain SVG elements, including rect and text, styled with CSS, and uses the Share Tech font for the labels.
