How to plot arrow line (directed graph)?

📊 Plotly Python

I want to plot an arrow line between nodes to indicate the direction of routes. I cannot find such a built-in function to do so. Is there a method to do this work?

my codes:

import plotly.graph_objects as go
import plotly.io as pio
import plotly

lon1 = [113.076843, 113.154191, 113.737213, 113.842405, 114.244183 ]
lat1 = [23.10993, 23.218533, 23.047626, 22.987975, 22.601581 ]

lon2 = [113.364738, 113.664108, 113.661705,114.244183]
lat2 = [22.997112, 22.878038, 22.869216, 22.601581]

lon_trip1 = lon1
lat_trip1 = lat1

lon_trip2 = lon2
lat_trip2 = lat2

fig = go.Figure()
fig.add_trace(go.Scattermapbox(
    mode="markers+lines",
    lon=lon_trip1,
    lat=lat_trip1,
    name="trip1", marker={'size': 10}))

fig.add_trace(
    go.Scattermapbox(
        mode="markers+lines",
        lon=lon_trip2,
        lat=lat_trip2,
        name="trip2",
        marker={'size': 10}))

fig.update_layout(
    margin={'l': 113, 't': 24, 'b': 22, 'r': 115},
    mapbox=dict(style='carto-positron',
                center=go.layout.mapbox.Center(lon=113.664, lat=22.878),
                pitch=0,
                zoom=8)
)


pio.write_image(fig,'C:/Users/Jie/Desktop/plot.png',width=1980, height=1080)
#plotly.offline.plot(fig, filename='C:/Users/user/Desktop/plot' + '.html')
fig.show()
