What It Is

Fractional Brownian motion with H=0.7 --- persistent (trend-following), smoother trajectories with long-range dependence

Interpretation

Standard analysis sees: smooth / autocorrelated; long-range memory (persistent); volatility-clustering (bursty); low-dimensional; nonstationary / drifting. The atlas additionally detects Nonstationarity:adf_pvalue.
