A static bar chart displays four colored bars with distinct heights, rendered as SVG rectangles. The red, green, yellow, and blue bars are positioned at different x-coordinates, with varying y-coordinates and heights that encode categorical data values. The chart uses raw SVG elements within an HTML document, specifying the `width`, `height`, and `viewBox` attributes on the root `<svg>` element. No JavaScript or external libraries are used; the visualization is achieved solely through declarative SVG markup.
