Display multiple values in col on barplot-CodePudding

So I have a column of my dataframe that looks like this:

10 first rows of the column expeditions['first_ascent_country']

0    New Zealand, USA, UK
1                      UK
2                  France
3               UK, Nepal
4                   India
5               W Germany
6                   Spain
7               W Germany
8            Japan, Nepal
9            Japan, Nepal

It gives information on which country climbed a mountain first. I want to display those countries in a barplot to show which ones discovered more, but I get this... How do I separate the countries using a comma?

Step by step:

>>> df['peak_ascent_country'].str.split(', ')
0    [New Zealand, USA, UK]
1                      [UK]
2                  [France]
3               [UK, Nepal]
4                   [India]
5               [W Germany]
6                   [Spain]
7               [W Germany]
8            [Japan, Nepal]
9            [Japan, Nepal]

>>> df['peak_ascent_country'].str.split(', ').explode().value_counts()
0    New Zealand
