DataViz.Layout.Hierarchy.EdgeBundle.RadialCluster

type RadialLayoutConfig = { endAngle :: Number, innerRadius :: Number, outerRadius :: Number, startAngle :: Number }

Configuration for radial cluster layout

defaultRadialConfig :: RadialLayoutConfig

Default configuration

data RadialNode a

A node with radial coordinates

Constructors

• RadialNode { children :: Array (RadialNode a), data_ :: Maybe a, depth :: Int, fullName :: String, height :: Int, name :: String, x :: Number, y :: Number }

Instances

• (Show a) => Show (RadialNode a)

radialCluster :: forall a. RadialLayoutConfig -> TreeNode a -> RadialNode a

Apply radial cluster layout to a tree

Algorithm:

1. Assign sequential indices to leaves (angular positions)
2. Position leaves evenly around the circle at outerRadius
3. Position internal nodes at mean angle of children, at appropriate radius

toCartesian :: forall a. RadialNode a -> { x :: Number, y :: Number }

Convert radial coordinates to Cartesian for SVG rendering

radialClusterFromTree :: forall a. TreeNode a -> RadialNode a

Convenience function: layout from a TreeNode using default config
