python漏斗图出不来

以下是两种Python绘制漏斗图的例子：
1. 使用pyecharts库绘制漏斗图[^1]：

from pyecharts import Funnel

# 初始化图形参数
funnel = Funnel("漏斗图", width=800, height=400)
# 添加数据
funnel.add("漏斗图", ["Website visit", "Downloads", "Potential customers", "Requested price", "invoice sent"], [39, 27.4, 20.6, 11, 2], is_label_show=True)

# 渲染图形到html文件
funnel.render("funnel.html")

2. 使用plotly库绘制漏斗图[^2]：

import plotly.graph_objects as go

fig = go.Figure(go.Funnel(
    y=["Website visit", "Downloads", "Potential customers", "Requested price", "invoice sent"],
    x=[39, 27.4, 20.6, 11, 2],
    textposition="inside",
    textinfo="value+percent initial",
    opacity=0.65
))

fig.show()

请注意，确保你已经安装了对应的库，用于绘制漏斗图。如果漏斗图仍然无法显示，请检查代码是否正确以及是否导入了所需的库。
