This isometric treemap visualizes the hierarchical structure of the Flare data set. The view uses an axonometric projection, rendering rectangular tree cells as three-dimensional blocks that appear to recede in space. Each subtree is assigned a distinct hue, while lightness decreases with nesting depth, making hierarchy easier to perceive. The visualization supports geometric zooming and panning via d3.behavior.zoom, with an interactive group element enabling exploration of the hierarchy. Hover effects or click interactions are not described in the provided code. The layout recursively partitions the hue range among child nodes and uses linear and sqrt scales to map depth and branching to luminance and chroma, respectively, creating a visually organized isometric treemap.
