When is a pie chart an appropriate choice for visualization?
Tests data viz principles for part-to-whole data. A good answer defines this use case, gives a clear example (market share), and lists pitfalls like too many slices or similar values. A red flag is defending them for complex data or time-series analysis.
Tests your grasp of data viz principles and choosing charts that avoid misleading interpretations. A strong answer defines the single valid use case: showing proportional composition of a static whole with 2-5 categories. Give a specific example like OS market share. Then, detail pitfalls like using >7 slices, which makes comparison impossible, or showing categories with very similar values. A red flag is suggesting pie charts for comparing datasets or showing trends over time, where bar or line charts excel.
