A simple SVG line drawing renders a single closed polygonal path with magenta strokes and black lines, based on hardcoded coordinate data. Built with React and ReactDOM, the example uses the SVG `path` element with a `d` attribute containing straight-line commands (M, L, and z) to define the shape inside a 960×500-pixel viewport. The code directly embeds the path data rather than loading external datasets, demonstrating basic SVG rendering capabilities within a React component.
