This example visualizes a sine wave using a series of circles plotted along the x-axis, with each circle’s vertical position computed as `Math.sin(a) * 200` and offset from the horizontal center. The chart is rendered as an SVG using React and ReactDOM, with 50 circles spaced 50 pixels apart across a 960×500 canvas. The code leverages React’s declarative component structure, mapping over an array of x-coordinates to generate circle elements, while the HTML loads React libraries and a separate `bundle.js` to run the visualization.
