One of Pajek's strongest features is its ability to generate 2D and 3D visualizations of networks. It uses various layout algorithms (such as Fruchterman-Reingold or Kamada-Kawai) to position nodes in a way that makes the network structure intelligible. Users can interact with these visualizations, zoom in on specific clusters, and export high-quality images for publication. zoom in on specific clusters
