Radial Dendrogram
A radial dendrogram displays the hierarchical structure of the Flare dataset as a circular tree, with leaf nodes positioned along the outer ring and internal nodes nearer the center. The visualization uses D3 v4's `d3.stratify` to build the hierarchy from a CSV, `d3.cluster` to compute the radial layout, and SVG paths for curved links. Node labels are rotated and positioned based on their angle relative to the center. The code loads data from `flare.csv`, which contains node identifiers and values.
