What type of worksheet is described as displaying data from various sources in a visual format?

The type of worksheet described as displaying data from various sources in a visual format is a treemap. A treemap visualizes hierarchical data using nested rectangles to represent different categories and subcategories, allowing users to quickly grasp the relationships and proportions of the data at a glance. This visualization technique is particularly effective in illustrating the size and hierarchical connections among a large amount of data, making it easier for stakeholders to identify patterns, trends, and insights.

In contrast, other options focus on different data presentation methods that may not emphasize visual formatting in the same way. For instance, a table-based worksheet typically organizes data in rows and columns without the visual hierarchy that a treemap provides. Composite worksheets combine elements from different data sources but may not necessarily offer the visual representation that highlights interconnections as effectively as a treemap. Transformation worksheets pertain more to the process of altering data formats or structures rather than showcasing them visually.
