一、项目预览

Image text

二、功能简介

  • 快捷菜单栏(上)

    下载示例数据、上传数据进行分析、导出编辑后的数据、导出图片、布局计算 开始/结束 控制、查找节点、全屏切换、以及留言、公共数据集、路径分析、图参数调节面板的显隐控制
  • 快捷工具栏(左上)

    网络图缩放、旋转
  • 可视控制区(左下)

    对网络图提示框、分类统计图、节点内文字、关系文字、关系箭头、贴心小提示进行显隐控制
  • 调色区(下)

    对节点颜色进行更改
    注:先选中后才能更改
  • 留言面板(右)

    对项目留言
  • 公共数据集选择面板(右)

    选择公共数据集进行可视化分析
  • 路径分析面板(右)

    输入两个节点的 index 进行路径分析
  • 图参数调节面板(右)

    对网络图的节点间斥力、连接强度、节点和边的缩放比例、边的类型、网络图布局方式、分析模式以及对背景颜色或图片进行调整,也可对批量节点的大小、透明度、边的宽度进行调节
    注:需先进行节点和边的选中,方可调节
  • 右键菜单

    • 右键点击空白区域,可进行节点创建
    • 右键点击关系,可进行关系打破
    • 右键点击节点,可进行节点扩展、节点删除、构建关系以及按条件选取

三、项目部署

  • linux

    安装 python3 运行环境

    1、yum install python36...
    2、yum install pip36...
    3、pip install django
    4、pip install py2neo

    安装java jdk

    5、yum install java-1.8.0-openjdk

    安装neo4j

    6、wget https://neo4j.com/artifact.php?name=neo4j-community-3.4.12-unix.tar.gz
    7、tar -xzvf neo4j-community-3.4.12-unix.tar.gz

    导入数据

    8、neo4j-admin import --nodes nodes.csv --relationships links.csv

    修改neo4j配置 远程访问并修改密码

    9、vim neo4j.conf
    10、把54行dbms.connectors.default_listen_address=0.0.0.0注释去掉
    11、远程访问neo4j数据库 http://IP:7474/ 修改初始密码

    拉取代码

    12、git clone https://github.com/iaboaix/NetworkGraph.git

    启动 neo4j 和 django

    13、neo4j start
    14、nohup python3 manage.py runserver --insecure 0.0.0.0:80 &
    15、访问 http://127.0.0.1/
  • windows

    安装 python3 运行环境

    1、安装python3.x
    2、安装python包
    3、pip install django
    4、pip install py2neo

    安装java jdk

    5、下载地址
    https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

    安装neo4j

    6、下载地址
    https://neo4j.com/download/
    7、导入数据
    neo4j-admin import --nodes nodes.csv --relationships links.csv
    8、访问neo4j数据库并修改初始密码
    http://127.0.0.1:7474/
    修改初始密码为xxxxxx

    拉取代码

    9、git clone https://github.com/iaboaix/NetworkGraph.git

    启动neo4j django

    10、neo4j start
    11、python3 manage.py runserver --insecure 0.0.0.0:80
    12、访问 http://127.0.0.1/
  • tips:

    1、启动之前,将服务器外网IP地址加入 django settings.py 的 ALLOWED_HOSTS
    2、若 django sqlite 报错
          vim /usr/local/lib64/python3.6/site-packages/django/db/models/base.py
          将版本检测代码段注释掉
    3、若 django debug = false 之后 静态文件找不到 启动时添加 --insecure

四、NetworkGraph.min.js模块使用方法

下载最新模块

NetworkGraph.min.js
