This pseudo bar chart presents four black rectangles of varying heights on a white background, simulating a simple categorical bar chart without axes, labels, or data values. The visualization is entirely hand-coded in raw SVG using the `rect` element for each bar, with inline styles controlling fill color and stroke width. It relies on explicit `width`, `height`, `x`, and `y` attributes to position and size the bars. The Inkscape namespace declarations indicate the chart was originally authored in the Inkscape vector editor before being exported.
