Social Network Visualizer

Features

• Draw nodes and edges with a few clicks on a virtual canvas, or import data from a file in a supported format. Right-click any element for context actions. Customise each node’s label, size, color, shape, and even use your own image as a node icon.
• Compute cohesion metrics (density, diameter, distances, clustering coefficient, reciprocity), centrality and prestige indices (betweenness, closeness, eigenvector, PageRank, and more), community detection (triad and clique census), and structural equivalence analysis.
• Apply layouts based on prominence scores (circular, radial, level), force-directed models (Kamada-Kawai, Fruchterman-Reingold, Spring Embedder), or the ego-centered radial layout to explore a node’s neighborhood in depth.
• Non-destructive filters let you isolate any part of the network — ego network, selection, attribute value, centrality score, or edge weight — without losing data. A persistent filter bar shows active conditions as chips you can clear one by one or all at once.
• Attach custom attributes to nodes and edges, browse and inline-edit everything in the Data Table dock (Ctrl+T), and export to CSV or JSON for bulk editing in any spreadsheet tool.
• Load and save networks in GraphML, GraphViz, GML, Pajek, UCINET, Adjacency, EdgeList, and two-mode sociomatrix formats. GraphML is the native format with full roundtrip support for custom attributes.
• Load, edit, and save networks with multiple relations. Switch between relations in the Control Panel without losing the others.
• Generate random networks using Barabási–Albert scale-free, Erdős–Rényi, Watts-Strogatz small-world, d-regular, and ring lattice models.
• Instantly recreate classic social network datasets such as Padgett’s Florentine families, Zachary’s Karate Club, and more.
• Automatically build a network of linked web pages by pointing the built-in crawler at any URL.
• A comprehensive manual covers every feature — available both online and inside the application via the Help menu.
• SocNetV is free and open-source (GPL3). Use it anywhere, contribute patches on GitHub, or report bugs.
• Low memory and CPU use
