The contrast between foreground and background colors

The total file size of the visualization

17. Which of the following is a characteristic of effective data visualization design?

Maximizing the number of colors used

Minimizing cognitive load while preserving information

Using decorative elements extensively

Avoiding axis labels to save space

Submit

19. In visual encoding, which principle states that the effectiveness of a channel depends on the data type being represented?

Weber's Law

Gestalt Principle

Data-Ink Ratio

Expressiveness and Effectiveness

20. What is the primary purpose of using a diverging color palette in data visualization?

To make the visualization more aesthetically pleasing

To represent data with a meaningful midpoint and opposing extremes

To reduce the file size of the visualization

To ensure colorblind accessibility
