            Could it be that you expect a certain Python installation (virtual environment) to be used in Jupyter, but Jupyter is using a different kernel?

            With that assumption, I believe all you need to do is to add the virtual environment to Jupyter as a kernel. In more detail:

            • Install & activate your virtual environment. Below I'll use virtualenv, which nowadays seems to be the recommended way of working (see Python docs), but there are other options as well:
              • pip install --user virtualenv if it is not installed yet (it is installed by default for the newer Python versions). By the way, personally, I use Poetry instead of pip for a while now, and I like it a lot.
              • Go to the desired directory (with cd ) and create the environment with python3 -m venv .
              • Activate the environment with source /bin/activate (deactivate with deactivate).
            • Make sure ipykernel is installed (pip install --user ipykernel)
            • Add the venv to Jupyter with python3 -m ipykernel install --user --name=.

            Now you should be able to select in Jupyter this environment as a kernel, and all packages installed in that venv should be picked up by Jupyter automatically as well (you'll need to restart the kernel in that case though).

            The name of the dataframe column, numpy.array, or pandas.Series to be plotted. If numpy.array or pandas.Series are used then it must have same length as dataframe.

            Text as tooltip, popup or labels in folium choropleth GeoJSON polygons

            Folium allow to create Markers with tooltip or popup text. I would like to do the same with my GeoJSON polygons.

            My GeoJSON has a property called "name" (feature.properties.name -> let's assume it is the name of each US state). I would like to be able to display this as a label in my choropleth map, in addition to the unemployment rate in each state. I also have the same information in the "State" column from the pandas dataframe.

            Is this possible? I would be happy with a solution that allows this to be a popup, tooltip or a simple text label written on top.

            1. Capture the return value of the Choropleth function
            2. Add a value(eg unemployment) to the Chorpleth's underlying geojson obj
            3. Create GeoJsonTooltip with that value from step 2

            The reason you could not draw the graph may be that the geometry of geopandas is a line segment. I got the zip code geojson file from here to deal with this. This file is in polygon format. Also, if you reference it as it is in goepandas, the key referenced in key_on will be 'feature.propeties.zipcode'. One important point is that the zip code to be associated with geojson is a string, so the user data must also be a string.
