This example shows a simple house built from basic SVG shapes by directly manipulating the DOM with D3.js. It uses `d3.select` to target the SVG canvas and appends rectangles, a polygon, and circles to construct the house, roof, windows, door, and doorknob. The code relies on D3's chained `.attr` methods to set coordinates, dimensions, and fill colors on each shape, while the accompanying stylesheet provides a light gray background for the SVG. The scene is static, with no interaction or animation.
