D3-React
This example demonstrates a minimal integration of D3 and React for SVG rendering. The code uses React to create a static SVG canvas containing a red circle with a black stroke, centered at 400 by 400 pixels. It specifically imports the `arc` function from D3 v6 via `d3.arc`, though the arc is not rendered in the final output. The visualization relies on React’s `render` method to mount the component into the `#root` div, with data defined as fixed constants for dimensions and styling.
