This example demonstrates a manual chart selector interface with buttons to load different SVG visualizations. The interface presents four buttons—Bar Chart, Scatter Plot, Histogram, and Line Chart—that trigger `loadSvg()` to fetch and inject raw SVG text into the page. Currently, only the Bar Chart uses a real external source from GitHub, while the other buttons reference placeholder URLs. The implementation relies on basic JavaScript `fetch()` calls and DOM manipulation via `innerHTML`. Styling is minimal, using inline CSS for the page body and button layout.
