A yellow monster face drawn with SVG primitives, featuring two eyes, a curved mouth, and angular brow lines, all centered on a radial gradient fill. The gradient shifts from purple to pink to gold across the circular head, while a drop shadow filter adds a cyan glow. Built with React and D3’s `arc` and `line` generators, the code constructs the mouth path and eyebrows using computed angles and coordinates, with D3 v5 handling the geometry.
