This example uses D3 v7 to draw a cartoon cat entirely from SVG primitives, combining circles, ellipses, lines, and paths to form the body, head, ears, eyes, nose, mouth, whiskers, and tail. Each element is created manually via `document.createElementNS` and appended to an SVG container, avoiding D3 data joins or scales. The static illustration uses fixed pixel coordinates and a gray, black, and pink palette, demonstrating direct SVG manipulation within a minimal HTML and CSS setup.
