A tree is a special graph, that is, a graph without a cycle. Tree data (TreeData) does not explicitly define edges, but implicitly represents edges through nested `children`, that is, there is an edge between parent and child nodes.
|
|
|
|
An example of a tree data is as follows:
|
|
|
|
```json
|
|
{
|
|
"id": "root",
|
|
"data": {},
|
|
"children": [
|
|
{
|
|
"id": "node-1",
|
|
"data": {},
|
|
"children": [
|
|
{
|
|
"id": "node-1-1",
|
|
"data": {},
|
|
"children": [
|
|
{
|
|
"id": "node-1-1-1",
|
|
"data": {},
|
|
"children": []
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
G6 5.0 can read `TreeData`, `TreeData[]`, that is, **tree** and **forest**.
