학술 상관관계 꺾은선형 차트

An academic line graph figure from a prestigious [economics paper], demonstrating a close but imperfect correlation between [the price of oil] and [the number of shark attacks] across [the years 1914 to 2001]. The chart features clean dual y-axes, distinct trend lines, labeled axes, a neat legend, subtle grid lines, traditional serif academic typography, and a formal figure caption at the bottom, styled like a scan of a printed scholarly journal.
