Invasion Percolation is the first network visualization of modern network science and the first generative network art.
It depicts a network generated by water penetrating the ground, and its formal representation is rooted in a square lattice, inspired by crystal lattices explored by physicists. The algorithm was built by Albert-László Barabási in 1994, and the surviving 1995 output opened the Hidden Patterns retrospective of BarabásiLab at ZKM Karlsruhe in 2021 and the Ludwig Museum in Budapest in 2020
