流程图（四）利用python绘制漏斗图

# 基本漏斗图
from plotly import 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]))

fig.show()

# 分类漏斗图
from plotly import graph_objects as go

fig.add_trace(go.Funnel(
    name = 'Montreal',
    y = ["Website visit", "Downloads", "Potential customers", "Requested price"],
    x = [120, 60, 30, 20],
    textinfo = "value+percent initial"))

fig.add_trace(go.Funnel(
    name = 'Toronto',
    orientation = "h",
    y = ["Website visit", "Downloads", "Potential customers", "Requested price", "invoice sent"],
    x = [100, 60, 40, 30, 20],
    textposition = "inside",
    textinfo = "value+percent previous"))

    x = [90, 70, 50, 30, 10, 5],
    textposition = "outside",
    textinfo = "value+percent total"))
