+### 4 图管理
 client支持一个物理部署中多个 GraphSpace，每个 GraphSpace 下可以含多个图（graph）。
 - 兼容：不指定 GraphSpace 时，默认使用 "DEFAULT" 空间

-#### 4.3 GraphSpace 中的图管理
-
-  在 GraphSpace 中，可以管理多个图：
-
-```java
-// 在指定的 GraphSpace 中创建图
-GraphsManager graphsManager = hugeClient.graphs();
-Graph graph = new Graph();
-graph.setName("businessGraph");
-graph.setDescription("Business relationship graph");
-graphsManager.createGraph("myGraphSpace", graph);
-
-// 获取 GraphSpace 中的所有图
-List<Graph> graphs = graphsManager.listGraphs("myGraphSpace");
-
-// 获取指定图
-Graph businessGraph = graphsManager.getGraph("myGraphSpace", "businessGraph");
-
-// 删除图
-graphsManager.removeGraph("myGraphSpace", "businessGraph");
-```

-#### 4.3 Graph Management in GraphSpace
-
-You can manage multiple graphs in a GraphSpace:
-
-```java
-// Create a graph in the specified GraphSpace
-GraphsManager graphsManager = hugeClient.graphs();
-Graph graph = new Graph();
-graph.setName("businessGraph");
-graph.setDescription("Business relationship graph");
-graphsManager.createGraph("myGraphSpace", graph);
-
-// Get all graphs in GraphSpace
-List<Graph> graphs = graphsManager.listGraphs("myGraphSpace");
-
-// Get the specified graph
-Graph businessGraph = graphsManager.getGraph("myGraphSpace", "businessGraph");
-
-// Delete graph
-graphsManager.removeGraph("myGraphSpace", "businessGraph");
-```
