Python Data Visualization (Matplotlib &
Seaborn) โ Complete Study Notes
Introduction
Data visualization is the graphical representation of data using charts, graphs, and plots. It
helps in understanding patterns, trends, and relationships within data.
In Python, data visualization is mainly done using libraries such as Matplotlib and Seaborn.
For data analysts, visualization is a crucial skill because it helps communicate insights
effectively.
Definition
Data visualization is the process of presenting data in visual formats such as charts and
graphs.
It simplifies complex datasets and makes it easier to interpret information.
In Python, visualization libraries provide tools to create various types of plots.
Matplotlib Overview
Matplotlib is a widely used library for creating static, animated, and interactive
visualizations.
It provides full control over graph customization.
It is considered the foundation for most Python visualization libraries.
Basic Plot Example
Example:
import matplotlib.pyplot as plt
x = [1,2,3,4]
y = [10,20,30,40]
plt.plot(x,y)
plt.show()
