This example shows a simple yellow circle with two black eyes and a curved mouth, resembling a smiley face rendered as SVG. The drawing uses D3 version 6 API functions, including `select` to reference the SVG element, `append` to create circles and a path, and `arc` to generate the mouth’s curved shape based on specified radii and angles. The chart uses a fixed 960×500 coordinate space with no external data, instead relying on manual positioning and styling through attribute assignments.
