Seaborn Python (How it Works for Developers Guide)

Introduction

Statistical data visualization Seaborn is a popular Python visualization library. It is built on top of the Matplotlib Python module and provides a high-level interface for drawing attractive and informative statistical graphics. Seaborn is particularly well-suited for visualizing complex datasets and making data analysis more intuitive. Later in this article, we will also look into IronPDF, a PDF generation and manipulation library from IronSoftware.

Key Features

1. High-Level Interface: Seaborn provides a high-level interface, simplifying the process of creating complex visualizations. This means you can make sophisticated plots with just a few lines of code.
2. Integration with Pandas: Seaborn works seamlessly with Pandas data structures, making it easy to visualize data stored in DataFrames.
3. Beautiful Default Styles: Seaborn comes with beautiful default styles and color palettes, which help make the plots more attractive and more accessible to interpret.

4. Statistical Estimation: Seaborn includes functions for estimating and plotting statistical relationships, such as regression lines and confidence intervals.

   5. Univariate and Bivariate distributions: Seaborn supports statistical data visualization with

   Univariate Distributions in Seaborn

   1. Histogram: Visualizes the frequency of data points in bins.

   2. KDE Plot: Shows a smooth curve representing data density.

   3. ECDF Plot: Displays the cumulative proportion of data points.

   4. Box Plot: Illustrates data distribution with quartiles and outliers.

   Bivariate Distributions in Seaborn

   **1. Scatter Plot**: Depicts the relationship between two variables. 
   
   **2. Hexbin Plot**: Uses hexagonal bins to show data density.
   
   **3. Bivariate KDE Plot**: Smooth density plot for two variables.
   
   **4. Pair Plot**: Shows pairwise relationships in a dataset.

Getting Started

To get started with Seaborn, you need to install it using pip:

pip install seaborn

pip install seaborn

Once installed, you can import Seaborn with import matplotlib and create visualizations. Here’s a simple 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(data=tips, x="total_bill", y="tip", hue="time")
plt.show()

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(data=tips, x="total_bill", y="tip", hue="time")
plt.show()

In this example, we load the “tips” dataset and create a scatter plot showing the relationship between the total bill and the tip amount, with different colors representing different times of the day.

Output

Commonly Used Plots

1. Relational Plots: These plots show relationships between variables. Examples include scatter plots and line plots.

   sns.relplot(data=tips, x="total_bill", y="tip", hue="smoker", style="time")
   plt.show()

   sns.relplot(data=tips, x="total_bill", y="tip", hue="smoker", style="time")
   plt.show()

   PYTHON

2. Categorical Plots: These plots visualize categorical data. Examples include bar plots, box plots, and violin plots.

   sns.boxplot(data=tips, x="day", y="total_bill", hue="smoker")
   plt.show()

   sns.boxplot(data=tips, x="day", y="total_bill", hue="smoker")
   plt.show()

   PYTHON

3. Distribution Plots: Examples include histograms and kernel density estimation and plots.

   sns.histplot(data=tips, x="total_bill", kde=True)
   plt.show()

   sns.histplot(data=tips, x="total_bill", kde=True)
   plt.show()

   PYTHON

4. Matrix Plots: These plots visualize data in matrix form. Examples include heat maps and cluster maps.

   glue = sns.load_dataset("glue").pivot(index="Model", columns="Task", values="Score")
   sns.heatmap(glue)
   plt.show()

   glue = sns.load_dataset("glue").pivot(index="Model", columns="Task", values="Score")
   sns.heatmap(glue)
   plt.show()

   PYTHON

Seaborn plots can also be used for distribution plot graphs, line plot graphs, box plots, and bar plots, and plotting code with real-world data or statistical data is effortless.

Customization

Seaborn allows extensive customization of plots. You can change the plot's style, color palette, and other aspects to suit your needs. For example, you can set the theme using:

sns.set_theme(style="whitegrid")

sns.set_theme(style="whitegrid")

Installation

pip install ironpdf

pip install ironpdf

Generate PDF Documents using IronPDF and Seaborn.

Prerequisites

1. Make sure Visual Studio Code is installed as the code editor.
2. Python version 3 is installed.

To start with, let us create a Python file to add our scripts

Open Visual Studio Code and create a file, seabornDemo.py.

Install necessary libraries:

pip install seaborn
pip install ironpdf

pip install seaborn
pip install ironpdf

Then add the below code to demonstrate the usage of IronPDF and Seaborn Python packages

import seaborn as sns
import matplotlib.pyplot as plt
from ironpdf import * 
# Apply your license key
License.LicenseKey = "your key here"
# Load an example dataset
tips = sns.load_dataset("tips")
print(tips)
# Seaborn note: Create a simple scatter plot
sns.scatterplot(data=tips, x="total_bill", y="tip", hue="time")
plt.savefig("scatterplot.png") # save same plot
ImageToPdfConverter.ImageToPdf("scatterplot.png").SaveAs("scatterplot.pdf")
plt.show()

import seaborn as sns
import matplotlib.pyplot as plt
from ironpdf import * 
# Apply your license key
License.LicenseKey = "your key here"
# Load an example dataset
tips = sns.load_dataset("tips")
print(tips)
# Seaborn note: Create a simple scatter plot
sns.scatterplot(data=tips, x="total_bill", y="tip", hue="time")
plt.savefig("scatterplot.png") # save same plot
ImageToPdfConverter.ImageToPdf("scatterplot.png").SaveAs("scatterplot.pdf")
plt.show()

Code Explanation

In this example, we will use the same tips data frame from the above example and plot the scattered plot. Then, save it as an image and convert it to PDF using IronPDF.

1. Add imports to the Python file: import seaborn as sns, import matplotlib.pyplot as plt, and from ironpdf import * .

2. Add the License key to start using IronPDF.
3. Load the sample dataframe "tips" which contains the information on the total bill and tips per bill.
4. Print the DataFrame loaded to see this in the output window.
5. Create the scattered plot using scatterplot method on seaborn package.
6. Save the plot using savefig method.
7. The next step is to create a PDF using IronPDF and save the image using the 'ImageToPdf' and 'SaveAs' methods, naming the file scatterplot.pdf.
8. The last step is to show the plot as a window. You can also display the PDF and check the plot at this stage.

Output

PDF

IronPDF License

IronPDF Python license key to allow users to test its comprehensive features before purchasing. After the trial license period, developers can purchase a perpetual license that fits their project needs.

Place the License Key at the start of the script before using IronPDF package:

from ironpdf import * 
# Apply your license key
License.LicenseKey = "key"

from ironpdf import * 
# Apply your license key
License.LicenseKey = "key"
