D3 Viz
This example shows a single yellow circle centered in an SVG canvas, demonstrating how React renders SVG elements. The code uses React and ReactDOM to create a circle with a yellow fill and black stroke, though the stroke-width prop is misspelled as "stoke-width" so the border does not appear. The SVG tag defines the canvas dimensions, and React manages the DOM rendering for the visualization, with no data sources or D3.js functions involved.
