#### 前言 ####

> 有时在开发中用过的一些比较好的功能没有及时封装，导致日后再用的时候还得再来一遍，现在是想将这些功能封装成组件，做到“”拿来即用“”，为了更好地照顾到版本兼容，我直接将资源下载到本地作为静态资源使用，这个组件基于vue2,如果你是个新手不会将之转为vue3或者react等框架，可以留言，我看到后会更新，这里默认大家具有一定经验。
> 
> --------------------
> 
> 这个组件的好处：相比于直接使用D3或者echarts，他的优点在于有大量已经内置的功能，且可以通过修改源码方式轻松定制，而不必从0开始写。具体更多的使用方式可以参考文档：

好了，言归正传，接下来的步骤是具体封装为全局组件。你如果跟着我的步骤使用，我确保你100%可以成功。

--------------------

### 使用 ###

--------------------

#### **第一步** ####

> public文件夹中， 将以下：
> 
> 一个css文件放入static下的css中；
> 
> 两个js文件放入static下的js文件中。

依赖源码：我去字数太多，发不出来，大家请自行下载吧。

neo4jd3.css:[https://github.com/eisman/neo4jd3][https_github.com_eisman_neo4jd3]

--------------------

d3.min.js:[https://github.com/eisman/neo4jd3][https_github.com_eisman_neo4jd3]

--------------------

neo4jd3.js :[https://github.com/eisman/neo4jd3][https_github.com_eisman_neo4jd3]

--------------------

#### 第二步  ####

> components文件夹下新建Neo4jD3文件夹，新建index.vue文件，复制以下代码粘贴过去，然后再index.js里注册全局组件
> 
> 类似这样：

> 
> main.js 里面引入vue.use一下即可

总结：

> 其实，你只需要复制最后的组件源码即可，至于怎么封装，完全看你心情，我只是提供一个方法，你也大可随便找个地方保存，引入使用即可。
> 
> 需要注意的地方也就是初始数据，注意格式即可。再就是要记得设置高度，我用的是rem单位，记得改一下。
