In which type of worksheet can users detect the root cause of problem areas through visualization?

The treemap is a type of data visualization that effectively represents hierarchical data using nested rectangles. In the context of detecting root causes of problem areas, this format is particularly beneficial due to its ability to display parts of a whole. Each rectangle within a treemap corresponds to a category and is sized and colored according to specific metrics, allowing users to quickly assess the proportions and variations across different segments.

Using a treemap, users can visually identify which areas are performing poorly compared to others, as the size and color gradients effectively highlight discrepancies. For instance, a larger segment or one that stands out in color may indicate a significant problem or opportunity for improvement. This immediate visual feedback aids in pinpointing the exact areas needing further investigation to determine the underlying causes of any issues.

The other types of worksheets mentioned do not provide the same level of immediate visual contrast or hierarchical display. Transformation and composite worksheets focus more on data manipulation and aggregation, while table-based formats organize information in rows and columns without the graphical representation that enhances intuitive understanding of complex relationships and areas of concern. Thus, the treemap excels in facilitating a clear and effective analysis of problem areas.
