如下图所示，那么就创建成功了。

如何图形化显示呢？
按照下图依次点击1,2，3，进行图形化显示。

上述是添加数据进入到图数据库，如何删除回到最初始的界面呢？

neo4j删除所有节点和关系

MATCH (n)
OPTIONAL MATCH (n)-[r]-()
DELETE n,r

把上述代码复制到这里，然后运行

就删除了

删除某个标签的所有节点

match (n : attribute) delete n

插入节点

CREATE 
 (p1:user {name:'Alice'}),
 (p2:attribute {name:'A学校'}),
 (p3:attribute {name:'B学校'}),
 (p4:attribute {name:'New York'}),
 (p5:attribute {name:'Google'}),
 (p6:attribute {name:'Office'}),
 (p7:attribute {name:'Finance'}),
 (p1)-[:高中学校]->(p2),
 (p1)-[:大学学校]->(p3),
 (p1)-[:工作城市]->(p4),
 (p1)-[:工作公司]->(p5),
 (p1)-[:技能]->(p6),
 (p1)-[:技能]->(p7)
 

删除与某个节点相关联的所有的边

MATCH (a:Artist {name: “筷子兄弟”}) DETACH DELETE a
