You will need to install the necessary libraries, such as Seaborn and Matplotlib, to run the examples. You can use the Python package manager called pip to install these libraries. Below are the commands you can use in your Python environment to install the libraries:

pip install seaborn matplotlib pandas

Distribution Plots

import seaborn as sns
import matplotlib.pyplot as plt

# Sample data in the form of a dictionary
data = {'values': [1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5]}

# Create a histogram with a KDE using Seaborn
sns.histplot(data=data['values'], kde=True)
plt.show()

Distribution Plots

Pair Plots

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Sample data in the form of a dictionary
data = {'var1': [1, 2, 3, 4], 'var2': [2, 4, 1, 3], 'var3': [3, 1, 4, 2]}

# Convert the dictionary to a pandas DataFrame
df = pd.DataFrame(data)

# Create a pair plot using Seaborn
sns.pairplot(df)
plt.show()

Pair Plots

Heatmaps

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Sample data in the form of a dictionary
data = {'var1': [1, 2, 3], 'var2': [4, 5, 6], 'var3': [7, 8, 9]}

# Convert the dictionary to a pandas DataFrame
df = pd.DataFrame(data)

# Create a heatmap using Seaborn
correlation_matrix = df.corr()
sns.heatmap(correlation_matrix, annot=True, cmap='coolwarm')
plt.show()

Heatmaps

Categorical Plots

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Sample data in the form of a dictionary
data = {'category': ['A', 'B', 'A', 'B'], 'value': [1, 2, 3, 4]}

# Convert the dictionary to a pandas DataFrame
df = pd.DataFrame(data)

# Create a box plot for categorical data using Seaborn
sns.boxplot(x='category', y='value', data=df)
plt.show()

Categorical Plots

Regression Plots

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Sample data in the form of a dictionary
data = {'x': [1, 2, 3, 4], 'y': [2, 4, 3, 5]}

# Convert the dictionary to a pandas DataFrame
df = pd.DataFrame(data)

# Create a regression plot using Seaborn
sns.regplot(x='x', y='y', data=df)
plt.show()

Regression Plots

Facet Grids

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Sample data in the form of a dictionary
data = {'category': ['A', 'B', 'A', 'B'], 'x': [1, 2, 3, 4], 'y': [2, 4, 3, 5]}

# Convert the dictionary to a pandas DataFrame
df = pd.DataFrame(data)

# Create a facet grid using Seaborn
g = sns.FacetGrid(df, col='category', margin_titles=True)
g.map(plt.scatter, 'x', 'y')
g.add_legend()
plt.show()

Facet Grids
