Introduction to Data Visualization
Data visualization plays a critical role in research by allowing you to explore datasets, communicate findings, and strengthen your arguments with clear, compelling visuals. When you visualize data, you can quickly identify trends, patterns, and outliers that may not be obvious from raw tables or summary statistics alone. Effective charts and graphs make it easier for others—such as collaborators, reviewers, or broader audiences—to understand your results and the story behind your data. Visualization is not just about making data look attractive; it is about making complex information accessible and actionable.

A typical matplotlib plot is made up of several basic components. The figure is the overall window or page that everything is drawn on. Inside the figure, the axes represent the area where the data is actually plotted—this is where you see the graph itself. Labels are used to describe the axes, so viewers know what the plotted data represents. Finally, the title provides a short description of the plot, helping viewers quickly understand what they are looking at. These components work together to make your data visualization informative and easy to interpret.

1. Why is data visualization important in research?
2. Which matplotlib function is used to plot a line graph?
3. What is the purpose of axis labels in a plot?
