Time-series data involves a variable that is a function of time, such as a company's stock price or daily temperature. Common visualization methods include line charts, multiple line charts for comparisons, area charts to emphasize magnitude, and stacked area charts for cumulative totals. The content provides a detailed tutorial on how to create these visualizations in Python using the Matplotlib library. It includes specific code examples and step-by-step explanations for building line charts, multiple line charts, area charts, and stacked area charts using a sample sales dataset.
