我想建立一个组织结构图。如下所示：A - B - C

B - C - D

A - E

这意味着A监督B和B监督C，C监督D，A监督E。我想知道是否可以用每个员工作为一个节点来建立一个树形图。在

有些代码如下所示，我不知道如何将其应用到我当前的人力资源数据中。在pip install python-igraph

import igraph

from igraph import Graph, EdgeSeq

nr_vertices = 25

v_label = list(map(str, range(nr_vertices)))

G = Graph.Tree(nr_vertices, 2) # 2 stands for children number

lay = G.layout('rt')

position = {k: lay[k] for k in range(nr_vertices)}

Y = [lay[k][1] for k in range(nr_vertices)]

M = max(Y)

es = EdgeSeq(G) # sequence of edges

E = [e.tuple for e in G.es] # list of edges

L = len(position)

Xn = [position[k][0] for k in range(L)]

Yn = [2*M-position[k][1] for k in range(L)]

Xe = []

Ye = []

for edge in E:

Xe+=[position[edge[0]][0],position[edge[1]][0], None]

Ye+=[2*M-position[edge[0]][1],2*M-position[edge[1]][1], None]

labels = v_label

import plotly.graph_objects as go

for k in range(L):

fig.show()

我不知道这些数字是怎么用圆圈表示的。相反，我希望员工的名字显示在圆圈里。

有人能帮忙吗？在
