This example demonstrates how to render custom geometric shapes—squares and triangles—in an SVG scene using D3.js v4. It defines a `shapeDefs` object with functions that construct SVG path strings via the `d3.path` API, and then uses a data join to draw the shapes. The code showcases the enter, update, and exit pattern by first rendering a dataset of three nodes, then re-rendering with a second dataset, which removes the red square. Each shape’s position and color are stored as data properties and applied through `transform` and `fill` attributes.
