Playfair’s Line Graph

Playfair’s Line Graph is a visual tool used to compare multiple sets of data over time or categories. It displays data points connected by lines, with each line representing a different category. The graph helps identify trends, patterns, and relationships among the groups quickly. By observing how the lines move up or down, viewers can see changes and differences clearly. It's especially useful when you want to compare several variables simultaneously and understand their behavior over a series of points or periods.
