How do you visualize hierarchical data?
Definition: Treemaps are visualizations for hierarchical data. They are made of a series of nested rectangles of sizes proportional to the corresponding data value. A large rectangle represents a branch of a data tree, and it is subdivided into smaller rectangles that represent the size of each node within that branch.
Which visualizations show hierarchical data in a nested format?
Treemaps. This method shows hierarchical data in a nested format. The size of the rectangles used for each category is proportional to its percentage of the whole. Treemaps are best used when multiple categories are present, and the goal is to compare different parts of a whole.
Which of the following visualization tool is most appropriate to compare different categories displayed in hierarchical relationships via rectangles?
Bar or column chart
Most commonly used to compare related data sets, bar charts organize data into rectangular bars proportional to the value it represents. The x-axis of a bar chart shows the categories that are being compared and the y-axis represents the value.
Which of the following visualization types is used for displaying the hierarchical relationships?
A tree visualization displays hierarchical data with a collection of nodes (data points) and edges (hierarchical relations between nodes). A normal tree visualization is the most commonly used type of hierarchal visualization. It is easy to interpret since the traditional tree structure is widely known.
