Is it possible to set a discrete symbol map for plotly scattermapbox. color and color_discrete_map can be used to assign a certain color but can the same approach be used to assign a specific symbol using a discrete map?

With below, I want to assign the symbol_dict to the unique values in species. Both px.scattermapbox or go.scattermapbox are viable.

The 2nd option doesn’t return an error but it also doesn’t show any of the points.

import plotly.express as px
import pandas as pd

df = px.data.iris()

symbol_dict = {'versicolor': 'star', 'setosa': 'circle', 'virginica': 'diamond'}
smap = df["species"].map(symbol_dict)

fig = px.scatter_mapbox(
    df,
    lat="sepal_width",
    lon="sepal_length",
    #symbol="species", # set symbol to species
    #symbol_map=symbol_dict, # set symbol to species
)

fig = go.Figure(go.Scattermapbox(
    lat=df['sepal_width'],
    lon=df['sepal_length'],
    mode='markers',
    marker=dict(symbol = smap)
    )
)

fig.update_layout(mapbox_style = "carto-positron")

fig.update_mapboxes(zoom = 5)

fig.show()
