This example shows a single yellow circle rendered as a smiley face, drawn in an SVG using React components. The circle is centered dynamically based on the viewport dimensions, with a black stroke and fixed stroke width. The code uses React 16.9 and ReactDOM to render the SVG element into the DOM, with the circle’s position and radius calculated from width and height variables. The rendering approach relies on declarative JSX to define the SVG, and the interactive video demonstrates the implementation.
