This example introduces D3 version 6 and 7 syntax by rendering basic SVG shapes—a pink circle and a red rounded rectangle—directly in an HTML page, with a fixed 960×500 SVG viewport. The code uses `d3.select` from the D3 library to append text to the document body, demonstrating the module’s import style. The accompanying README and embedded YouTube tutorial guide users through version differences. Rendering relies on plain SVG markup for shapes, not data joins or interactive features, serving as a minimal starting point for learning D3’s setup and drawing primitives.
