The visualization displays a collection of basic geometric shapes—an ellipse, rectangle, and circle—colored individually and grouped to illustrate SVG styling and transformation. A second group applies a uniform fill and stroke, while a line and an unclosed path demonstrate stroke properties and line joins. The example is built with d3.v5, using the `select` API to target the SVG, and relies on raw SVG elements and CSS classes for rendering, with a fixed viewport enforced by the stylesheet.
