# XWUIChartDendrogram

A dendrogram: a graph-family chart (extends `XWUIChartGraphBlockBase` with a
top-to-bottom `tree` layout, not the Cartesian `XWUIChart`) that draws a hierarchy as
a branching tree. Supply the hierarchy through `nodes`, where each node has a `name`,
a `value`, and optional `children`; pick a `size` (`sm` / `md` / `lg`). Use
it to show nested structure such as taxonomies, org charts, or clustering results.

## Basic Usage

A small `Root → A/B/C` hierarchy (with `A` split into `A1`/`A2`) drawn as a top-down
tree at the md size preset.

## Org Reporting Structure

A company headcount hierarchy fanning out from the CEO into divisions and their sub-teams.

```example

```

## Mammal Classification

A biological taxonomy from class down to genus, showing nested scientific classification as a tree.

```example
file: examples/SpeciesTaxonomy.ts
html: examples/SpeciesTaxonomy.html
title: Mammal Classification
description: A Mammalia-to-genus taxonomy rendered as a top-down dendrogram with interactive nodes.
