How might a scientist display data on the territories of different groups of chimpanzees? what would this be an example of?

The data on the territories of three groups of chimpanzees can be displayed using a heat map overlayed over the geographical map. The heat map would show the population sizes, and the boundary of the heat map would define the territories of the chimpanzees. This helps one in quick interpretation and analysis of the data. This method of visualising the data is called data visualisation.  

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.
