This visualization displays a forest of hierarchical decision trees, each representing a model with an associated accuracy score. The trees are color-coded by accuracy—red for high (≥0.8), blue for medium (≥0.6), and gray for low—allowing viewers to compare structural complexity and performance across models. The code uses D3 v5’s `d3.tree` layout to compute node positions, with the SVG rendered and animated via D3’s selection and transition methods. Multiple trees are placed horizontally within a scrollable container, and interactions highlight nodes sharing the same name across different trees.
