import pandas as pd
import matplotlib.pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

pathcsv = r'D:\iPython\csvfile\samplecsv2.csv'
df = pd.read_csv(pathcsv)
df.set_index('Names').plot()

plt.show()

ax =df.set_index('Names').plot()
ax.set_xticks(np.arange(len(df))) #Show ticks for each country
ax.set_xticklabels(df.Names)      #Show labels as in df.Names
plt.show()
