Jeden obraz jest wart więcej niż tysiąc słów.
aiSee automatically calculates a customizable layout of graphs specified in GDL (graph description language). This layout is then displayed, and can be printed or interactively explored.

Features
- Fast layout calculation for huge graphs
- Award-winning layout readability
- Zooming and easy navigation
- Subgraph nesting and various subgraph operations:
- Folding of complete subgraphs
- Folding of user-defined connected regions
- Hiding of edges
- 15 graph layout methods, including a specialized version for trees
- Animation interface (visualization of a series of graphs and smooth transitions)
- Export of complete graphs and selected graph parts to various formats, including SVG, PNG, HTML (image maps), and colored PostScript (on multiple pages for large graphs)
Application fields
Back in 1991, aiSee was developed to visualize the internal data structures typically found in compilers. Today it is widely used in many different areas:
- Genealogy (family trees, evolution diagrams, pedigrees)
- Business management (organization charts)
- Software development (call graphs, control flow graphs, validation of hardware traces)
- Hardware design (circuit diagrams, finite state diagrams)
- Bioinformatics (gene expression graphs, signaling pathways, consensus genetic maps)
- Database management (entity relationship diagrams)
- Informatics (finite state automata, algorithm visualization)
- Web design and Web site optimization (sitemaps, visitor movement graphs)
- Network analysis (P2P networks, IRC networks, social networks, the Internet)
- Linguistics (syntax trees, grammar graphs, term variant graphs)
- Criminology (fraud networks, felony event flow diagrams)
aiSee reads a textual, easy-to-read and easy-to-learn graph specification and visualizes the graph. Its design has been optimized to handle large graphs automatically generated by applications (e.g. compilers). It can also be easily integrated into other applications, including Web-based ones.
aiSee runs under Windows, Linux, and Mac OS X. It is available free of charge for non-commercial usage.
