This example uses D3.js v7 to draw a stylized pizza as an SVG composition of concentric circles and evenly distributed toppings. The code builds the pizza from a light-brown dough base, tomato-red sauce, and golden cheese layer, then adds spinach ellipses and purple pepperoni circles positioned mathematically using trigonometric formulas, along with randomly placed chili flakes. All elements are created through D3's `select`, `append`, and `attr` chain on an SVG canvas, with toppings positioned using polar coordinates converted to Cartesian coordinates.
