What is Data Visualization?

Data visualization is the graphical representation of information and data. By using visual elements like charts, graphs, and maps, data visualization tools provide an accessible way to see and understand trends, outliers, and patterns in data.

Introduction to Matplotlib

Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Pyplot is a state-based interface to matplotlib that provides a MATLAB-like way of plotting.

Installation:

pip install matplotlib

Basic Import and Setup

import matplotlib.pyplot as plt
import numpy as np

# Basic plot
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]
plt.plot(x, y)
plt.show()
