Charts

Definition

Charts are visual representations of data that help to communicate information clearly and efficiently. They can take many forms, such as bar graphs, line charts, pie charts, and scatter plots, making complex data more digestible and easier to analyze. In predictive analytics, charts play a crucial role in illustrating trends, patterns, and relationships within data sets, thereby enhancing the interpretability of results in reports.
