+## Mutation Type Visualization
+
+The library supports various mutation strategies that affect how the genetic algorithm explores the search space. The visualization below shows how different mutation types explore a 2D search space when searching for a target point:
+
+![Mutation Types Exploration Patterns](examples/visualize_mutation_types.png)
+
+The visualization demonstrates:
+- **Random**: Chaotic exploration, can jump anywhere in search space
+- **Range**: Local search with fixed radius around current position
+- **RangeScaled**: Adaptive exploration that starts broad and narrows down (funnel-like convergence)
+- **Step**: Fixed-step local search in cardinal directions
+- **StepScaled**: Grid-like exploration with progressively finer resolution
+
+Run the example with `cargo run --example visualize_mutation_types --release` to generate this visualization.

 ## Heterogeneous Genotype Support
 
 MultiRangeGenotype supports heterogeneous chromosomes that mix different gene
