mergeEdges

Elk specific option that allows edges to share path where it convenient. It can make for pretty diagrams but can also make it harder to read the diagram.

mergeEdges

• is optional

• Type: boolean

• cannot be null

• defined in: Mermaid Config

mergeEdges Type

boolean

nodePlacementStrategy

Elk specific option affecting how nodes are placed.

nodePlacementStrategy

• is optional

• Type: string

• cannot be null

• defined in: Mermaid Config

nodePlacementStrategy Type

string

nodePlacementStrategy Constraints

enum: the value of this property must be equal to one of the following values:

Value	Explanation
"SIMPLE"
"NETWORK_SIMPLEX"
"LINEAR_SEGMENTS"
"BRANDES_KOEPF"

nodePlacementStrategy Default Value

The default value is:

"BRANDES_KOEPF"

cycleBreakingStrategy

This strategy decides how to find cycles in the graph and deciding which edges need adjustment to break loops.

cycleBreakingStrategy

• is optional

• Type: string

• cannot be null

• defined in: Mermaid Config

cycleBreakingStrategy Type

string

cycleBreakingStrategy Constraints

enum: the value of this property must be equal to one of the following values:

Value	Explanation
"GREEDY"
"DEPTH_FIRST"
"INTERACTIVE"
"MODEL_ORDER"
"GREEDY_MODEL_ORDER"

cycleBreakingStrategy Default Value

The default value is:

"GREEDY_MODEL_ORDER"

forceNodeModelOrder

The node order given by the model does not change to produce a better layout. E.g. if node A is before node B in the model this is not changed during crossing minimization. This assumes that the node model order is already respected before crossing minimization. This can be achieved by setting considerModelOrder.strategy to NODES_AND_EDGES.

forceNodeModelOrder

• is optional

• Type: boolean

• cannot be null

• defined in: Mermaid Config

forceNodeModelOrder Type

boolean

considerModelOrder

Preserves the order of nodes and edges in the model file if this does not lead to additional edge crossings. Depending on the strategy this is not always possible since the node and edge order might be conflicting.

considerModelOrder

• is optional

• Type: string

• cannot be null

• defined in: Mermaid Config

considerModelOrder Type

string

considerModelOrder Constraints

enum: the value of this property must be equal to one of the following values:

Value	Explanation
"NONE"
"NODES_AND_EDGES"
"PREFER_EDGES"
"PREFER_NODES"

considerModelOrder Default Value

The default value is:

"NODES_AND_EDGES"
