Description: Graphical overlay is a data visualization technique that involves placing one graphical representation over another to facilitate the comparison of different data sets. This methodology allows analysts and decision-makers to observe patterns, trends, and relationships that may not be evident when examining data in isolation. Graphical overlays can include various types of representations, such as line graphs, bar charts, area charts, or maps, and are commonly used in contexts where understanding how different variables relate to each other is crucial. By overlaying graphs, correlations, divergences, and anomalous behaviors can be identified, enriching the analysis and interpretation of the data. This technique is especially valuable in fields such as economics, meteorology, biology, and engineering, where data comparison is fundamental for informed decision-making. The visual clarity provided by graphical overlay helps communicate complex information more accessibly, allowing users to quickly grasp the essence of the presented data.
