Pseudo Bar Chart
This pseudo bar chart uses four rectangles to represent data values as vertical bars on an SVG canvas. It uses HTML and CSS to create a full-bleed, borderless viewport, along with JavaScript for potential interactivity (though none is currently implemented). The code directly specifies the `x`, `y`, `width`, and `height` attributes on each `<rect>` element, creating a bar chart with bars of varying heights and no axes or labels. The chart is rendered using the SVG API within an HTML document.
