IIBA Exam CBDA Topic 3 Question 15 Discussion

Actual exam question for IIBA's CBDA exam

Question #: 15
Topic #: 3

A real estate broker is tracking monthly sales between two of its teams. The results have been visualized using a Treemap chart. What is the advantage of using a Treemap chart, over a Sunburst chart to visualize the results?

AWith its colour scheme, it is easy to compare the variables within a Treemap

BWith its rectangles and straight lines, a Treemap is optimized to include more

CA Treemap is meant to represent a hierarchical result set as opposed to a Sunburst chart

DA Treemap shows all the hierarchical levels of data as opposed to a Sunburst chart
Explanation:
A Treemap chart is a type of chart that displays hierarchical data as a set of nested rectangles, where the size and color of each rectangle represent a quantitative value and a categorical variable, respectively1.A Sunburst chart is a type of chart that displays hierarchical data as a set of concentric circles, where the size and color of each slice represent a quantitative value and a categorical variable, respectively2. Both charts are useful for visualizing hierarchical data structures, but they have different advantages and disadvantages.One advantage of using a Treemap chart over a Sunburst chart is that a Treemap chart is optimized to include more data points, as it uses a Cartesian coordinate system that fills the entire rectangular space of the chart area, whereas a Sunburst chart uses a polar coordinate system that leaves empty spaces in the corners of the chart area3. This means that a Treemap chart can display more levels of hierarchy, more categories, and more details than a Sunburst chart, without compromising readability or clarity.Therefore, the correct answer is B, as a Treemap chart is optimized to include more data than a Sunburst chart.

A Treemap is clearly the way to go here. The color scheme makes it super easy to compare the variables, no doubt about it!
