The automatic generation of drawings of graphs has important applications in key computer science technologies such as database design, software en-. Automatic graph drawing algorithms, especially those for hierarchical digraphs, have an important place in computer‐ aided design software or more generally in software programs where an ef cient visualization tool for complex structure is required. In these cases, aesthetics plays a major role for generating readable and understandable layouts. The call graph drawing interface is a set of small tools to visualize dynamic call graphs of c/ c+ + programs. It uses gprof to detect the function call structure of a test run, and uses the vcg tool to visualize this structure.

It is great for debugging and documentation purposes. See the call graph drawing interface page for more information. Simultaneous graph drawing: layout algorithms and visualization schemes?
