Geospatial and Map-Based Data Visualizations

1. What is a major limitation of choropleth maps?

They cannot show continuous data

Larger regions may appear more important due to visual weight

They require precise point locations

They cannot use color scales

2. Which of the following is a key principle when designing effective map-based visualizations for college-level audiences?

Use as many colors as possible

Ensure the map legend is clear and the data is properly contextualized

Eliminate all labels to reduce clutter

Always use the Mercator projection
