This example visualizes insertions into a self-balancing red-black binary tree, animating each new node as it traverses the tree and recolorings occur. The tree layout is computed with `d3.forceSimulation`, applying force-directed positioning with gravity toward parent nodes and depth-based vertical placement. The visualization renders on both SVG and Canvas, selectable via radio buttons, using `d3-quant` and `d3-canvas-transition` to share code between rendering backends. A random uniform generator supplies node values, and insertions trigger timed animations that update the tree structure incrementally.
