IIBA Exam CBDA Topic 1 Question 8 Discussion

Actual exam question for IIBA's CBDA exam

Question #: 8
Topic #: 1

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.

I see your point, Wade. A Treemap does show hierarchical levels of data better than a Sunburst chart.

I think C is the correct answer, as a Treemap is meant to represent hierarchical data unlike a Sunburst chart.

That's a good point, Shonda. The colour scheme does play a role in the comparison between variables.

But don't you think the colour scheme in a Treemap makes it easier to compare variables compared to a Sunburst chart?

I agree with you, Stevie. A Treemap is optimized to show more information with its rectangles and straight lines.

I think the advantage of using a Treemap chart over a Sunburst chart is its ability to include more data points.

So the correct answer is B, right? Because Treemap is optimized to include more data.

I prefer Treemap over Sunburst because it can show all hierarchical levels of data.

Yes, that's correct. A Treemap is optimized to include more data with its rectangles.

Haha, 'maximizing that real estate,' An? You've been spending too much time around those brokers, haven't you? But I have to say, I agree with the general consensus here. If the question is specifically about advantages, then a Treemap does seem like the way to go. More data, more details, more of what the brokers are looking for. Sunbursts are nice, but they might not cut it in this case.

Totally, more data, more details. A Treemap seems like the way to go in this case.

This is a real estate broker we're talking about, people. You know they're all about that botTwanna line. If a Treemap can pack in more data and make it easier to compare the variables, then that's what they're going to want. Sunbursts are great and all, but they're more for the artsy crowd. This is all about maximizing that real estate, baby!

I don't know, you guys. I kind of like the elegance of a Sunburst chart. It's like a data pizza, you know? And who doesn't love a good data pizza? But I guess if the question is specifically about advantages, then a Treemap does sound like the way to go. Rectangles and straight lines may not be the most exciting, but they sure do get the job done.

Yeah, I'm with Melita on this one. Treemaps are like the SUVs of the data visualization world - they just pack more in. And if this is for a real estate broker, you know they're going to want to see all the nitty-gritty details, right? Sunbursts are more for the artsy-fartsy crowd, if you ask me.

I don't know, Lavonda. The way I see it, a Treemap is all about maximizing that real estate, pun intended. If you want to cram more data into that chart, it's the way to go. Sunbursts are pretty and all, but they can get a little sparse, if you ask me.

Hmm, a Treemap chart over a Sunburst chart, huh? I'm not sure I'm feeling that. Rectangles and straight lines? Sounds a bit too rigid for my taste. I'm more of a curves and circles kind of guy, you know?
