+*Figure 41-4. Example of a multi-chart infographic sample from the dataset (Shark Attacks), consisting of four distinct subcharts covering three categories of statistics: historical shark-attack county ranking in the United States, state-level shark attacks in the last ten years, and average annual accidental deaths in the United States. The original figure is vertically elongated and hard to read as a whole; it is thus divided into horizontally aligned subfigures.*
The example is one integrated science infographic. Its internal regions belong to different chart types, statistical scopes, and data dimensions, while sharing the page title and side annotations:

案例原图为一张一体化科普信息图,内部被天然划分为四大独立子图分区,四个子图分属不同图表类型、不同统计口径、不同数据维度,同框排布、共用页面标题与侧边注释:
