Generate G6 AntV Dagre layout configuration

This function creates a configuration list for G6 AntV Dagre layout with all available options as parameters. The Dagre layout is designed for directed graphs, creating hierarchical layouts with nodes arranged in layers.

Usage

dagre_layout(
  rankdir = c("TB", "BT", "LR", "RL"),
  align = c("UL", "UR", "DL", "DR"),
  nodesep = 50,
  ranksep = 100,
  ranker = c("network-simplex", "tight-tree", "longest-path"),
  nodeSize = NULL,
  controlPoints = FALSE,
  ...
)

Arguments

rankdir: Layout direction: "TB" (top to bottom), "BT" (bottom to top), "LR" (left to right), or "RL" (right to left)
align: Node alignment: "UL" (upper left), "UR" (upper right), "DL" (down left), or "DR" (down right)
nodesep: Node spacing (px). When rankdir is "TB" or "BT", it's the horizontal spacing of nodes; when rankdir is "LR" or "RL", it's the vertical spacing of nodes.
ranksep: Interlayer spacing (px). When rankdir is "TB" or "BT", it's the spacing between adjacent layers in the vertical direction; when rankdir is "LR" or "RL", it represents the spacing between adjacent layers in the horizontal direction.
ranker: The algorithm for assigning a level to each node: "network-simplex" (the network simplex algorithm), "tight-tree" (the compact tree algorithm), or "longest-path" (the longest path algorithm)
nodeSize: G6 custom attribute to specify the node size uniformly or for each node. Can be a single number (same width/height), an array [width, height], or a function that returns either.
controlPoints: Whether to keep the control points of the edge
...: Additional parameters to pass to the layout

Value

A list containing the configuration for G6 AntV Dagre layout

Examples

# Basic dagre layout
dagre_config <- dagre_layout()

# Custom dagre layout with horizontal flow
dagre_config <- dagre_layout(
  rankdir = "LR",
  nodesep = 80,
  ranksep = 150,
  ranker = "tight-tree"
)

# Custom dagre layout with specific node size
dagre_config <- dagre_layout(
  nodeSize = 40,
  controlPoints = TRUE
)
