Example line geometries with different Hurst exponents. The curves represent examples of fractional Brownian motion, where correlations or anti-correlations are introduced between subsequent increments (Kroese and Botev 2015). The Hurst exponent H can be set in the model and H=0.5 corresponds to classical Brownian motion. a H=0, b H=0.5, c H=1. Each circular subplot magnifies the content of a small grid cell
