Visualizes randomly generated 2D spatial data and its corresponding empirical semivariogram.
- Left plot shows data points (X, Y) colored by value (Z). Higher noise increases value randomness.
- Right plot shows scaled semivariance vs. lag distance. Points represent bin averages; lighter points show approx. +/- 1 Std. Dev. bounds.
- Semivariance (Y-axis) is scaled to [0, 1]. Lag distance (X-axis) adjusts automatically based on data and number of bins.
