--- title: Dendrogram order: 14 --- Dendrogram arranges all the leaves on the same level. It is appropriate for hierarchical clustering. It does not consider the node size, which will be regarded as 1px. img ## direction **Type**: String
**Options**: 'LR' | 'RL' | 'TB' | 'BT' | 'H' | 'V'
**Default**: 'LR'
**Required**: false
**Description**: The direction of layout. - TB —— Root is on the top, layout from the top to the bottom img - BT —— Root is on the bottom, layout from the bottom to the top img - LR —— Root is on the left, layout from the left to the right img - RL —— Root is on the right, layout from the right to the left img - H —— Root is on the middle, layout in horizontal symmetry. img - V —— Root is on the middle, layout in vertical symmetry. img ## nodeSep **Type**: Number
**Default**: 0
**Required**: false
**Description**: Node separation ## rankSep **Type**: Number
**Default**: 0
**Required**: false
**Description**: Level separation ## radial **Type**: Boolean
**Default**: false
**Required**: false
**Description**: Wheter layout the graph in radial style. If `radial` is `true`, we recommend to set `direction` to `'LR'` or `'RL'`:
