This example renders a tidy tree layout using D3’s `d3.tree` within a React component. It draws hierarchical nodes and links with SVG paths, positioning them via the computed `x` and `y` coordinates from the tree layout. The code imports React, ReactDOM, and d3 v6, but only logs the initial data and library objects to the console—no interactive behavior or data loading is visible. The visualization demonstrates a static, clean arrangement of parent-child relationships without animation or user interaction.
