This example shows how to construct a tree-like path structure using D3’s SVG rendering. It depicts a branching visualization where nodes are positioned on a grid and connected by curved Bézier paths. The code uses `d3.path` and `bezierCurveTo` to draw smooth edges, with `d3.scaleLinear` mapping coordinates to the SVG canvas. The implementation defines a recursive function to generate node pairs, then renders the paths via `selectAll` and `.attr("d")` in a static layout.
