SVG Creation
This example shows a stylized SVG face composed of concentric circles and an arc-based mouth, centered within a 960x500 viewport. The face includes cyan and pink eyes offset symmetrically from the center, with a stroke-defined outer boundary. Built with React, it renders SVG elements declaratively, while d3’s `arc()` generates the mouth path. Fixed coordinates and constants control all geometry, with no interactive or data-driven behavior.
