桑基圖繪制

桑基圖還是很簡單的，直接調用pyecharts就行，套用我的代碼即可實作。

注意：1.節點名稱唯一。

2.關系用的節點必須是已經建立的。

首先上效果圖：

代碼如下：

#coding='utf-8'
from pyecharts import options as opts
from pyecharts.charts import Sankey
#問題是節點名稱不能一樣
#所有關鍵詞和主題詞是節點，然後在同一年份的目标指向是主題詞；主題詞間又根據時間進行指向
#更新：四個關鍵詞為一行，一個主題詞為一行，間隔一行為年
nodes=[   # 所有節點名稱
    #關鍵詞，使用字尾無空格代表15-16，字尾一個空格代表17-18，字尾兩個空格代表19-20
