Matplotlib Examples: Creating Scatter Plots, Bar Charts, and Histograms in Python

📚 Quick Study Guide

• 📊 Scatter Plots: Used to display the relationship between two continuous variables. Created using plt.scatter(x, y).
• 📈 Bar Charts: Used to compare categorical data. Created using plt.bar(x, height).
• ⚙️ Histograms: Used to show the distribution of a single variable. Created using plt.hist(x, bins).
• 🎨 Customization: Matplotlib allows extensive customization of plots, including titles, labels, colors, and more.
• 🐍 Import: Always start with import matplotlib.pyplot as plt.
