如何绘制树形图

from pyecharts import options as opts
from pyecharts.charts import Tree

# 定义树形结构
tree_data = [
   {
       "name": "A",
       "children": [
           {"name": "B", "children": [{"name": "E"}, {"name": "F"}]},
           {"name": "C", "children": [{"name": "G"}, {"name": "H"}]},
       ],
   },
   {"name": "D", "children": [{"name": "I"}, {"name": "J"}]},
]

# 创建树形图
tree = Tree()
tree.add("", tree_data)

# 设置树形图配置项
tree.set_global_opts(title_opts=opts.TitleOpts(title="树形图"))

# 渲染树形图
tree.render("tree.html")
