Graphical perception refers to the human ability to interpret information presented in graphs and charts. It is important for statistical graphics design to ensure clarity, accuracy, and precision in data display. Cleveland and McGill's experiments have shown that relative position on a common scale is the most accurately perceived element in graphs, while angles and color hues are perceived with less accuracy. Visual pre-attentive processing can enhance the effectiveness of graph design by utilizing the brain's ability to perceive patterns. Choosing the appropriate graph type and considering principles of accuracy, clarity, and transparency are essential in creating effective graphical representations of data.
