如何 plot map 使用 geopandas 和 matplotlib

Question

there seems to be an issue with my code. My goal is to plot a map that represents an outcome (population) accross the regions of Benin.

import pandas as pd
import matplotlib as mpl

database_path = "datafinalproject.csv"
database = pd.read_csv(database_path)
#Creating a geodataframe
points = gpd.points_from_xy(database["longitude"], database["latitude"], crs="EPSG:4326")
map = gpd.GeoDataFrame (database, geometry=points) 

I get this message when I type map.plot and I when I type map.plot(column='population') , I get an empty map.

Can you help me solve this problem? database.head() gives:

Answer 1

map.plot() will work in a Jupyter notebook but not in a normal Python environment.

You should import matplotlib.pyplot and add plt.show() at the end of your code:

import pandas as pd
import geopandas as gpd
import matplotlib.pyplot as plt

database_path = "datafinalproject.csv"
database = pd.read_csv(database_path)
#Creating a geodataframe
points = gpd.points_from_xy(database["longitude"], database["latitude"], crs="EPSG:4326")
map = gpd.GeoDataFrame (database, geometry=points) 
map.plot()

plt.show()
