Generate G6 AntV Concentric layout configuration

This function creates a configuration list for G6 AntV Concentric layout with all available options as parameters. The Concentric layout places nodes in concentric circles based on a centrality measure.

Usage

concentric_layout(
  center = NULL,
  clockwise = FALSE,
  equidistant = FALSE,
  width = NULL,
  height = NULL,
  sortBy = "degree",
  maxLevelDiff = NULL,
  nodeSize = 30,
  nodeSpacing = 10,
  preventOverlap = FALSE,
  startAngle = 3/2 * pi,
  sweep = NULL,
  ...
)

Arguments

center: The center position of the circular layout [x, y] or [x, y, z]. By default, it's the center position of the current container.
clockwise: Whether nodes are arranged in clockwise order
equidistant: Whether the distances between rings are equal
width: The width of the layout. By default, the container width is used.
height: The height of the layout. By default, the container height is used.
sortBy: Specify the sorting basis (node attribute name). The higher the value, the more central the node will be placed. If it is "degree", the degree of the node will be calculated. The higher the degree, the more central the node will be placed.
maxLevelDiff: If the maximum attribute difference of nodes in the same layer is undefined, it will be set to maxValue / 4, where maxValue is the maximum attribute value of the sorting basis. For example, if sortBy is 'degree', then maxValue is the degree of the node with the largest degree among all nodes.
nodeSize: Node size (diameter). Used to prevent collision detection when nodes overlap. Can be a number, a 2-element vector [width, height], or a function that returns a number.
nodeSpacing: Minimum distance between rings, used to adjust the radius. Can be a number, a vector of numbers, or a function that returns a number.
preventOverlap: Whether to prevent node overlap. Must be coordinated with the nodeSize attribute or the data.size attribute in the node data. Only when data.size is set in the data or the nodeSize value that is the same as the current graph node size is configured in the layout, can node overlap collision detection be performed.
startAngle: The arc at which to start layout of nodes (in radians)
sweep: If the radian difference between the first and last nodes in the same layer is undefined, it will be set to 2 * Math.PI * (1 - 1 / |level.nodes|), where level.nodes is the number of nodes in each layer calculated by the algorithm, and |level.nodes| is the number of nodes in the layer.
...: Additional parameters to pass to the layout

Value

A list containing the configuration for G6 AntV Concentric layout

Examples

# Basic concentric layout
concentric_config <- concentric_layout()

# Custom concentric layout with degree-based sorting and overlap prevention
concentric_config <- concentric_layout(
  clockwise = TRUE,
  sortBy = "degree",
  preventOverlap = TRUE,
  nodeSize = 30,
  nodeSpacing = 20
)

# Custom concentric layout with specific center and dimensions
concentric_config <- concentric_layout(
  center = c(300, 300),
  width = 600,
  height = 600,
  equidistant = TRUE,
  startAngle = pi
)
