Four horizontal bars, colored orange, red, green, and blue, with varying widths, sit on a white background, each outlined in black. The visualization uses basic Scalable Vector Graphics (SVG) primitives—`rect` elements defined directly in the HTML—to create a static, pseudo-chart that mimics a stacked bar layout. No JavaScript libraries or data-binding frameworks are present; the rendering is purely declarative, with positions and dimensions hard-coded in the markup and styling provided by a simple external stylesheet.
