DataViz.Layout.Hierarchy.EdgeBundle.BundleCurve

bundlePath :: Number -> Array BundlePoint -> String

Generate SVG path for a bundle curve given points Uses quadratic Bezier spline approximation with bundle tension

The beta parameter controls tension:

• beta = 0: control points are not adjusted (straight-ish curve)
• beta = 1: control points follow the path exactly (maximum bundling)

bundlePathRadial :: Number -> Array { angle :: Number, radius :: Number } -> String

Generate bundle path from radial coordinates Takes (angle, radius) pairs and converts to Cartesian for rendering

bundlePathCartesian :: Number -> Array { x :: Number, y :: Number } -> String

Generate bundle path from Cartesian coordinates directly

type BundlePoint = { x :: Number, y :: Number }

A point on the bundle path

beta :: Number

Default beta (tension) value - D3's default
