Question 340
An analyst needs to compare percentage shares of five customer segments at one point in time, with simple categories. What can work?
Explanation
Correct Answer
Use a donut chart sparingly for a small number of distinct parts. Donut charts show part-to-whole shares, but become hard to read with many segments.
Incorrect Answers
Use a treemap for hierarchical part-to-whole comparison. This solves “Category and Subcategory with space allocated by contribution”; the stated issue is “at one point in time, with simple categories”.
Composition charts show how components change across a time axis. The deciding difference is “the month-by-month composition of online versus store sales” versus “at one point in time, with simple categories”.
Waterfalls display how successive changes produce a final total. That is a different operating condition from “at one point in time, with simple categories”: “from opening balance through adjustments to closing balance”.
