Quizplus · Accepted Answer

A bar chart displaying levels of average consumption per person for different age classes at a point in time represents a cross-sectional graph. Cross-sectional graphs display data for a specific point in time, rather than over a period of time (which would be a time-series graph), and typically show differences or comparisons between different groups or categories (such as different age classes in this case). The graph is not three-dimensional and there is no indication that it is inverted.
