Differences in each tesselation
-Original: Visually, it is represented the best. The downfall is that it differs the most in standard deviation, which doesn’t help when trying to do something with equal area.
-Square/Hexagon: These tesselations have the least standard deviation and because they are displayed to be equally represented, it results in the least amount of features.
-Voronoi: This tesselation has the greatest variance in the sizes, but is the closest to the original tesselation
-Triangulation: This tesselation provides twice as much features which improves it accuracy, but process slower.
