Another option to avoid the problem of points overlap is the increase the size of the dot depending on how many points lie in that spot. So, larger the size of the point more is the concentration of points around that.

Count_Strip_Plots.py

# Imports
import numpy as np
import pandas as pd
import matplotlib as mpl
import matplotlib.pyplot as plt
import seaborn as sns

# Import Data
df = pd.read_csv("https://raw.githubusercontent.com/selva86/datasets/master/mpg_ggplot2.csv")
df_counts = df.groupby(['hwy', 'cty']).size().reset_index(name='counts')

# Draw Stripplot
fig, ax = plt.subplots(figsize=(16,10), dpi= 80)    
sns.stripplot(x=df_counts.cty, y=df_counts.hwy, sizes=(df_counts.counts*20), hue=df_counts.counts, ax=ax)

# Decorations
plt.title('Counts Plot - Size of circle is bigger as more points overlap', fontsize=22)
plt.show()

Right.
