This example presents a static bar chart built with D3.js, displaying a hardcoded array of twelve numeric values. The SVG output renders green bars on a light background, with each bar’s height directly proportional to its data value. The code uses D3’s selection API and `selectAll` with chained `attr` methods to position bars, explicitly setting the SVG dimensions, bar width, and vertical offset. The data is a simple local JavaScript array, not fetched from an external source.
