Package-level declarations

Layout result types, transformation utilities, and bounding box helpers. TreeLayoutResult is a concrete class providing chainable coordinate transforms (mapped, centered, scaledTo, normalized, translated). LayoutTransition enables animated interpolation between two layout states. Extension functions toJson and fromJson provide zero-dependency JSON serialization.

Types

Bounds

data class Bounds(val minX: Float, val minY: Float, val maxX: Float, val maxY: Float)

Axis-aligned bounding box of a tree layout.

LayoutTransition

class LayoutTransition<T>(from: TreeLayoutResult<T>, to: TreeLayoutResult<T>)

Represents a transition between two layout states, enabling animation by interpolating node positions at a given progress fraction.

TreeLayoutResult

class TreeLayoutResult<T>(positions: Map<T, Point>, maxDepth: Int)

The result of a tree layout computation, providing access to node positions, layout metadata, and transformation utilities.

Functions

fromJson

fun <T> TreeLayoutResult.Companion.fromJson(json: String, keyToNode: (String) -> T): TreeLayoutResult<T>

Deserializes a TreeLayoutResult from a JSON string previously produced by toJson.

toJson

fun <T> TreeLayoutResult<T>.toJson(nodeToKey: (T) -> String): String

Serializes a TreeLayoutResult to a JSON string.
