This example shows a stylized smiley face, a circle filled with yellow and outlined in black, with elaborate white and black elliptical eyes and a pink mouth with a black outline. The entire face is drawn as a group of SVG shapes, centered within an 960x500 viewport. The visualization uses React to declaratively define the SVG elements, leveraging ReactDOM to render the application to the page. The code positions the face and its parts using computed constants for coordinates and dimensions, and it applies transformations to group elements for the eyes and mouth.
