Cartography and Geospatial Analysis Questions

Multiple choice

What is the purpose of a heat map in data visualization?

  1. To display the distribution of data

  2. To compare multiple data sets

  3. To identify correlations or trends

  4. To show the relationship between two variables
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A heat map is a data visualization technique that uses colors to represent the magnitude of a variable. It is often used to identify correlations or trends in data by displaying the strength of the relationship between different variables.

Multiple choice

Which data visualization technique is suitable for displaying the hierarchical structure of data?

  1. Treemap

  2. Sankey diagram

  3. Bubble chart

  4. Radar chart
