Which of the following statements regarding data visualization is TRUE?

Tree maps are a data visualization technique that display hierarchical data using rectangles divided into smaller regions. The size, color, or placement of each rectangle can help communicate relative volume, grouping, or importance within the hierarchy. Option A is incorrect because keyword size and frequency are associated more closely with word clouds, not geospatial analysis. Geospatial analysis concerns location-based data. Option C is incorrect because color-coding and compatibility may improve visual communication, but they are not the core objectives of data visualization. Option D confuses link analysis with geospatial mapping; link analysis is used to show relationships among people, entities, transactions, accounts, or events. Therefore, the statement about tree maps is the accurate description.
