Visustin is a flow chart generator that converts code to diagrams automatically.

Visualize your source code with flow charts. Visustin charts your code automatically with a clear layout. Understand existing code. Review algorithms. Verify correctness of program logic. Document complex procedures. Visustin supports VB, VB.NET, VBA, ASP, QuickBASIC and other BASICs, C/C++, C#, Java, JSP, JavaScript, COBOL, Pascal/Delphi, Perl, PHP, T-SQL, PL/SQL and Ada. No matter what kind of code you need to document, Visustin can reverse engineer its underlying structure. All control flow structures such as conditionals, loops, jumps, premature exits and error handling statements are visualized automatically in an easy-to-understand format. No new languages to learn - your existing code is all you need. If you see a real complex case, print it out as a mosaic and hang it on your wall. Visustin automatically positions the flow chart elements for maximum readability. You can also use Visustin to create flow charts for Microsoft Visio, where you can edit them. Supported save file formats: GIF, BMP, JPG, PNG, HTML, MHT, Visio 2002/2003, EMF, WMF and PostScript.
