- Histogram
- Treemaps
- Bar charts
- None of the mentioned above
Answer: B) Treemaps
Explanation:
Treemaps are a great technique to represent hierarchical and part-to-whole relationships in a small space. Each tree branch is shown as a rectangle, with the size of each branch proportional to a defined data metric. Many people prefer treemaps because they're visually appealing, so knowing how to use colour is advantageous. In a treemap, colour is frequently used to indicate dimensions; heat maps are useful for displaying a spectrum.
