Add a polygon layer to a Choroplethmapbox

I have a Choroplethmapbox like that:

I’d like to add another layer representing the county’s border, that is, a “transparent” one showing only the border lines.

How can I do that?

Tks in advance,

Mauro Assis

Hi @assismauro,

Here https://chart-studio.plotly.com/~empet/15660
Is a notebok with an example that illustrate how you can add boundary lines as layers.

Tks, empet, it works like a charm.
