Using Dropdown to make traces visible

Dash Python
1

Hi, I’ve built a plotly express mapbox_scatter and set all the traces to “legendonly.” I want to be able to use a dropdown to change an individual traces visible=True. I cannot for the life of me understand why the below is not working. I am an excellent programmer, but Python is a relatively new language to me, and this is my first Dash project.

A solution would be nice, an explanation would be better.

Thanks!

Figure layout

fig = px.scatter_mapbox(bsird5_geo, lat=“Latitude”, lon=“Longitude”, color=“CAPABILITY”,
hover_name=“community_name”, size=“pct_all_funds”,
hover_data=(“CAPABILITY”, “HSGP”, “pct_all_funds”),
center={‘lat’: 40, ‘lon’: -140}, zoom=2, width=1080, height=900)

fig.update_layout(mapbox_style=“open-street-map”, showlegend=False)

fig.update_traces(marker={“sizeref”: .001, “sizemode”: “area”, “sizemin”: 1}, visible=“legendonly”)
