This interactive tree visualization displays the hierarchical relationships derived from a diabetes dataset, with color-coded nodes representing different attribute types such as Glucose, Insulin, BP, Age, and Outcome. Built with D3 v3, the visualization uses a collapsible tree layout with SVG rendering and animated transitions. Users can click nodes to expand or collapse branches, while tooltips provide additional context about each node. The tree employs `d3.layout.tree` to compute positions, with custom collision detection to prevent overlapping nodes based on the data structure loaded from a JSON file.
