How to add space in the top of my bar plot?

How to add space in the top of my bar plot? Here, i'm using seaborn and matplotlib to make the bar plot.

sns.set_style('darkgrid')

fig = plt.figure(figsize=(8,5))
plots = sns.barplot(x = ['Positif', 'Negatif'], y = data['label'].value_counts(), palette=['#588b8b','#c8553d'])

for bar in plots.patches:
    plots.annotate(format(bar.get_height(), '.2f'), 
                   (bar.get_x() + bar.get_width() / 2, 
                    bar.get_height()), ha='center', va='center',
                   size=12, xytext=(0, 8),
                   textcoords='offset points')
    
plt.xlabel("sentiment", size=12)
plt.ylabel("count", size=12)
plt.suptitle("Value Count\nPositive and Negative Label", size=16)
plt.show()
