9.3 Matplotlib for Data Visualization

Matplotlib turns your data into charts so you can actually see patterns, not just stare at numbers.

Chapter 9: Tools and Technologies for AI

Matplotlib is Python's classic charting library. Line charts, bar charts, scatter plots, histograms - all a few lines of code away.

Visualising data is a huge part of AI work: you plot data to spot outliers before training, and you plot training loss to check the model is actually learning.

Libraries like Seaborn and Plotly build on the same ideas with prettier defaults and interactive charts.

Key takeaways

Matplotlib = charts from data

Plot data before training and loss during training

Seaborn/Plotly for prettier or interactive charts
