Where did a human rights violation occur? What locations or regions are affected by a particular policy? What is the difference between urban and rural areas? How are things distributed spatially?
Displaying points on a map can contextualize where specific incidents took place. In addition to contextualizing specific events, mapping can reveal spatial patterns and gaps. Tools like choropleth maps, heat maps, and satellite images are useful for displaying geographic information.
Geographic information can also be a useful tool for finding correlations between two data sets, for instance funding of schools and the locations of different populations.
However, just because the data is geographic does not mean it needs to be displayed on a map. For instance, a ranked list or scatter plot may be more appropriate depending on your analysis and story.
