This fork of a smiley face visualization renders a single yellow circle with a black outline using React and SVG. The code computes the center coordinates and stroke width as constants, then passes them to the circle’s `cx`, `cy`, `r`, and `stroke-width` attributes. It uses ReactDOM to mount the component into a root div, with the SVG viewport set to 970 by 600 pixels. The example demonstrates a basic step toward building a face, though the eye circles remain incomplete due to placeholder offset values.
