0、概述
本文以热播电视剧《人民的名义》中的人物关系为数据基础，抛开案例本身的内容，本项目的意义在于指出使用Neo4j数据库的一般流程是什么？包括数据的导入、操作、查询、展示，从而体会出与传统数据库相比Neo4j在处理图数据的巨大威力和方便之处。
1、准备节点数据
Merge (n:People {name:"蔡成功",image:"caichenggong.png"})
Merge (n1:People {name:"欧阳青",image:"ouyangqing.png"})
Merge (n2:People {name:"李达康",image:"lidakang.png"})
Merge (n3:People {name:"沙瑞金",image:"sharuijin.png"})
Merge (n4:People {name:"高玉良",image:"gaoyuliang.png"})
Merge (n5:People {name:"侯亮平",image:"houliangping.png"})
Merge (n6:People {name:"赵东来",image:"zhaodonglai.png"})
Merge (n7:People {name:"陆亦可",image:"luyike.png"})
Merge (n8:People {name:"周正",image:"zhouzheng.png"})Merge (n110:People {name:"陈海",image:"chenhai.png"})

Merge (n117:People {name:"高玉良",image:"gaoyuliang.png"})
Merge (n118:People {name:"吴慧芬",image:"wuhuifen.png"})
Merge (n119:People {name:"钟小艾",image:"zhongxiaoai.png"})

Merge (n11c:People {name:"陈阳",image:"chenyang.png"})
Merge (n11s:People {name:"梁璐",image:"lianglu.png"})
Merge (n11w:People {name:"高小琴",image:"gaoxiaoqin.png"})
Merge (n11d:People {name:"郑西坡",image:"zhenxipo.png"})
Merge (n11g:People {name:"高小凤",image:"gaoxiaofeng.png"})2、准备关系数据

Match (n:People {name:"侯亮平"}),(b:People {name:"陆亦可"}) Merge(n)-[:下属]->(b)
Match (n:People {name:"侯亮平"}),(b:People {name:"赵东来"}) Merge(n)-[:办案]->(b)
Match (n:People {name:"赵东来"}),(b:People {name:"陆亦可"}) Merge(n)-[:喜欢]->(b)
Match (n:People {name:"陆亦可"}),(b:People {name:"陈海"}) Merge(n)-[:喜欢]->(b)
Match (n:People {name:"陆亦可"}),(b:People {name:"周正"}) Merge(n)-[:下属]->(b)
Match (n:People {name:"陆亦可"}),(b:People {name:"林华华"}) Merge(n)-[:下属]->(b)

Match (n:People {name:"高小琴"}),(b:People {name:"高小凤"}) Merge(n)-[:姐妹]->(b) 
3、人物关系分析
# 六层关系理论：世界上任何2个人的关系都不超过6层
Match p=allshortestpaths((N:People {name:'蔡成功'})-[*..6]-(m:People {name:'季昌明'})) return p
4、使用D3.js对Neo4j进行可视化
Neo4j browser 是面向数据分析人员的，Neo4j browser现成的效果是没法在Web系统里进行可视化展示或者嵌入，必须使用D3插件重新实现eo4j browser的某些功能。
具体该怎么做，Neo4j官网有相关的说明(https://neo4j.com/developer/tools-graph-visualization/#_visualization_resources)，其效果图如下，（官网也是使用D3.js实现的，效果远不如Neo4j官网）：
5、总结
本项目Web结构代码稍多，并且是某个培训机构的代码，这里就不方便贴出了，上面的讲课内容也大部分出自该课程。最后这个项目懂的java前端开发的容易做出来，这里的重点还是应用Neo4j自带的可视化功能，并且Neo4j本身的可视化功能已经很优秀了。
