Can you calculate the centroid of a contour line?
This figure can be any polygon as long as it is non-self-intersecting and the vertices are given in order of occurrence. This can be used to calculate e.g. the “real” centroid of a matplotlib contour line. Here is the code for the example above and the implementation of said algorithm:
