Module 'dash_leaflet.express' has no attribute 'choropleth'

Dash Python

Hi,

We’re using dash and dash_leaflet for a mapping and charting project. I created a new environment and installed the latest version of everything in Python 3.8.10, now our code throws the error:

module ‘dash_leaflet.express’ has no attribute ‘choropleth’

I think that this is caused by our call to “go.Choroplethmapbox”, but I can reproduce this with a simple script:

from dash_leaflet import express
express.choropleth()

Versions installed are below. Was choropleth removed, or is this a bug?

dash 1.20.0 pypi_0 pypi
dash-bootstrap-components 0.12.2 pypi_0 pypi

OK, I figured out a fix. Including:

style=dlx.choropleth.style

was causing the problem, removing that line fixed the issue and didn’t change the map. I think that the line was copied from an earlier example bit of code, so the code that now works is:

us_counties = dl.GeoJSON(
    data=counties,
    id='water_prices',
    options=dict(),
        hideout=dict(colorscale=color_scale, classes=classes, style=style, color_prop="comm_price"),
    )
