1) What type of graph is shown in the image above?

2) How are dead zones represented on the graph?

3) How is the human footprint or degree of human influence represented on the graph?

1. The graph above is a human footprint map basically to understand where we are able to make our colonies and civilization better.

(Can be called as a population influence graph).

2. The dead zones above are the areas where it shows less or very less footprints, for eg : The green region in the graph can be the most uncomfortable or dead zone for humans.

3. The degrees of human influence on graph is represented as follows :
