This visualization renders a pizza using SVG circles and ellipses layered to depict the crust, sauce, cheese, spinach, purple pepperoni, and chili flakes. Built with D3 v7, the code uses `d3.select` to append elements and JavaScript loops with trigonometric functions to position toppings evenly around the center. Random chili flakes are placed using `Math.random()` to scatter dots across the pie.
