D3 Intro with React
A simple SVG face rendered through React demonstrates how React’s declarative component model can be used to draw D3-like visualizations. Using React and ReactDOM, the code declaratively defines three circles—a yellow face with a black stroke and two black eyes—positioned via hardcoded coordinates and inline style attributes for stroke width. The SVG output is static, with no data or interaction; it illustrates the basic integration of React’s JSX syntax with SVG primitives to produce vector graphics.
