| TreeData | 2 |
The TreeData type is the type of tree graph data, which is one of the data types accepted by the Graph class. In version 5, the Graph and TreeGraph are connected, meaning that the same Graph class can read both the GraphData format and the tree graph data format described in this document. TreeGraph is a nested data structure that represents the parent-child hierarchy of a tree. Unlike GraphData, TreeData does not explicitly define edges and does not have an edges array. Instead, the nested children implicitly represent the edges, meaning that there is an edge between parent and child nodes.
In version 5, the Graph class can read GraphData, TreeData, and TreeData[], which means it can display graph data, tree graph data, and forests of multiple trees.
Properties
id
- Required: Yes;
- Type:
string | number;
The unique ID of the node. Once the node is created, the ID cannot be modified.
data
- Required: Yes;
- Type:
NodeUserModelData;
The data of the node, excluding the ID. It is recommended to store business data in this property. If data transformation is needed, it can be done through the transform configuration of the Graph instance, see Specification.transforms. The transformed data becomes the internal circulating data (Inner Data), and all subsequent accesses will obtain this internal data. Mapping related to rendering can be done through the node mapper of the Graph instance, see Specification.node. The input of this mapper is the Inner Data, and the generated Display Data is only consumed by the renderer. Users will not get it anywhere.
children
- Required: False;
- Type:
TreeData;
The array of child nodes of this node. It is a nested TreeData format node.
