一、基本思维导图

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from pyecharts.charts import  Tree
data = [
    {
        "name" : "python变量",
        "children" : [
            {"name":"字符串",
             "children":[{"name":"实例1：'abc'"},{"name":"实例2：'123abc'"}]},
            {"name":"列表",
             "children":[{"name":"实例1：[a,b,c]"},{"name":"实例2:[1,2,3]"}]},
            {"name":"字典",
             "children":[{"name":"实例1：{1:'a',2:'b'}"},{"name":"实例2：{a:[1,2,3],'2':(1,2,3)}"}]},
            {"name":"元组",
             "children":[{"name":"实例1：(1,2,3)"},{"name":"实例2:(a,b,c)"}]}
        ]

    }
]

c=(
    Tree()
    .add("",data)
)
c.render('swdt.html')

整个数据是1个列表，列表内只有1个字典元素，字典以“name”为键的值为思维导图的起点，以“children”为键的值为name的下一节点，其值仍为列表格式，依次类推。

二、向左发散思维导图

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from pyecharts.charts import  Tree
data = [
    {
        "name" : "python变量",
        "children" : [
            {"name":"字符串",
             "children":[{"name":"实例1：'abc'"},{"name":"实例2：'123abc'"}]},
            {"name":"列表",
             "children":[{"name":"实例1：[a,b,c]"},{"name":"实例2:[1,2,3]"}]},
            {"name":"字典",
             "children":[{"name":"实例1：{1:'a',2:'b'}"},{"name":"实例2：{a:[1,2,3],'2':(1,2,3)}"}]},
            {"name":"元组",
             "children":[{"name":"实例1：(1,2,3)"},{"name":"实例2:(a,b,c)"}]}
        ]

    }
]

c=(
    Tree()
    .add("",data,collapse_interval=3,layout="orthogonal",orient="RL")
)
c.render('swdt.html')

collapse_interval：代表分支之间的间隔
orient：正交布局，对应有 水平 方向的 从左到右，从右到左；以及垂直方向的从上到下，从下到上。取值分别为 ‘LR’ , ‘RL’, ‘TB’, ‘BT’。

三、径向分布思维导图

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# author : sunbo time : 2022/2/22 0022

from pyecharts.charts import  Tree
data = [
    {
        "name" : "python变量",
        "children" : [
            {"name":"字符串",
             "children":[{"name":"实例1：'abc'"},{"name":"实例2：'123abc'"}]},
            {"name":"列表",
             "children":[{"name":"实例1：[a,b,c]"},{"name":"实例2:[1,2,3]"}]},
            {"name":"字典",
             "children":[{"name":"实例1：{1:'a',2:'b'}"},{"name":"实例2：{a:[1,2,3],'2':(1,2,3)}"}]},
            {"name":"元组",
             "children":[{"name":"实例1：(1,2,3)"},{"name":"实例2:(a,b,c)"}]}
        ]

    }
]

c=(
    Tree()
    .add("",data,collapse_interval=3,layout="radial",)
)
c.render('swdt.html')

layout:代表布局，有2种形式，上述两种为’orthogonal’正交分布，'radial’代表径向分布，请大家注意，径向分布下orient参数是没有意义的

四、圆形思维导图

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# time : 2022/2/22 0022

from pyecharts import options as opts
from pyecharts.charts import  Tree
import  requests,json
response = requests.get("http://echarts.apache.org/examples/data/asset/data/flare.json")
data = json.loads(response.text)
c = (
    Tree()
    .add("",
         data=[data],
         pos_top="18%",
         pos_bottom="14%",
         layout="radial",
         symbol="emptyCircle",
         symbol_size=7,
         ).set_global_opts(
        tooltip_opts=opts.TooltipOpts(trigger="item", trigger_on="mousemove")
    )
)
c.render('swdt.html')

pos_top：tree组件离容器上侧的距离
pos_bottom：tree 组件离容器下侧的距离
symbol：标记的图形
symbol_size：标记的大小
