jGRASP is a lightweight freeware development environment for improving the comprehensibility of software via automatic generation of software visualizations.

jGRASP is implemented in Java and will run on all platforms with a Java Virtual Machine (Java version 1.5 or higher). It produces Control Structure Diagrams (CSDs) for Java, C, C++, Objective-C, Python, Ada, and VHDL; Complexity Profile Graphs (CPGs) for Java and Ada; UML class diagrams for Java; and has dynamic object viewers and a viewer canvas that work in conjunction with an integrated debugger and workbench for Java.

The viewers include a data structure identifier mechanism which recognizes objects that represent traditional data structures such as stacks, queues, linked lists, binary trees, and hash tables, and then displays them in an intuitive textbook-like presentation view. Java 6 or higher is required to run jGRASP.
