The image is a tree map that visually represents different categories and their frequencies. The largest section is labeled 'performance' with a frequency of 212, which is 14 percent of the total. Other significant categories include 'model' with 69 occurrences, 'sustainability' with 116, and 'management' with 89. Each category is further divided into subcategories with their own frequencies and percentages. For example, under 'performance,' subcategories include 'impact,' 'model,' 'energy,' 'optimization,' 'innovation,' and 'design.' The tree map uses different colors to distinguish between these categories and subcategories, providing a clear visual hierarchy. The frequencies and percentages are displayed within each colored section, indicating the relative importance or prevalence of each category and subcategory.Tree map
