Visual representations comprise most of the geography questions in the College Scholastic Ability Test, and geographic graphs have the highest relative ratio among the visual representations. The purpose of this study was to investigate the graph types and characteristics used in the geography questions of the CSAT from 2005 to 2015. The major findings are as follows. First, there are three graph presented types, and of these, only one graph type is present, at least two graph types are duplicated, and one graph type appeared mixed with other visual representations. Second, geographic graphs are divided into simple graphs (bar, line, circle, band, and scatter) and complex graphs (radial, triangle, stock price fluctuation, combo, picture, and others). The highest-proportion type is the line graph, followed by the bar, scatter, band, picture, and circle graphs, among the 11 graph types. Finally, the relative use of the graph ratio of human geography (on the theme of economic and population geography) is very high. Based on the quantitative percentage, the subject-specific application characteristics appeared on the themes of climate, natural resources, and population structure, each with a combo, a circle, and a bar graph.
