This example demonstrates a range of HTML elements, including forms with inputs, tables with employee data, nested lists, and SVG graphics with shapes, a gradient chart, and a landscape scene. Built with React and rendered as SVG, it uses vanilla JavaScript to handle form submission, row selection, and hover/click interactions on SVG elements. The code applies CSS Grid and Flexbox for responsive styling and includes a gradient navigation header, with all assets self-contained in a single file.
