This code produces the chart below:
import pandas as pd
df = pd.read_csv('https://www.dropbox.com/s/1bl0q007595d8am/2015.csv?dl=1') # data loading
df.plot(y=['Family', 'Freedom'], kind='hist')Output:
What is the minimum score of Family? To answer the question you have to add something to the code and run it. Keep in mind that score is plotted on the x-axis.
Tip: Try to change the transparency of the histograms.
