in a book about data visualization I came across the Bertin’s visual variables. There is size, shape, value, hue, texture, orientation and position. The book states, that we can present quantitative data with size, value and position. I agree with size and value, but I do not understand how I can present quantitative data with position. For a larger integer, I can for example increase the size of the point and make it darker (value). If someone could provide me an example for position, I would be very thankful.
Looking forward to your answers. Greetings ProblemStudent.
