This icicle diagram visualizes the hierarchical structure of the Flare dataset using a partition layout, where each node’s rectangular area is proportional to its value. The visualization is rendered with SVG and uses a categorical color scale to distinguish top-level categories. The layout is non-zoomable in this version, with labels centered on leaf nodes, and the tree is arranged from root at the left to leaves at the right, with depth shown horizontally and value shown vertically. The partition layout recursively subdivides the width based on each node's value relative to its siblings, creating a static, space-filling view of the hierarchy.
