Key Features of Seaborn Plotting

• Data-Centric: Seaborn works well with data frames from Pandas, a popular library for data manipulation.
• Ease of Use: Creating a plot is simple. You can create different types of plots, such as bar plots, scatter plots, line plots, and box plots, using a few commands.
• Customization Options: If you want to change colors, styles, or labels, Seaborn makes it easy to customize your plots to fit your needs.

Types of Plots in Seaborn

1. Scatter Plots: Show the relationship between two continuous variables.
2. Bar Plots: Display quantities for different categories clearly.
3. Line Plots: Useful for showing trends over time.
4. Box Plots: Help to visualize the distribution of data and identify outliers.
5. Heatmaps: Show the correlation between two sets of data using color.

Getting Started with Seaborn Plotting

To start using Seaborn, you need to install it using pip. Simply run the following command:

pip install seaborn

Once installed, you can import Seaborn into your Python script and begin creating plots. For example:

import seaborn as sns
import matplotlib.pyplot as plt

# Load an example dataset
tips = sns.load_dataset("tips")

# Create a simple scatter plot
sns.scatterplot(x="total_bill", y="tip", data=tips)
plt.show()

This code will display a scatter plot showing the relationship between total bill amounts and tips.
