pfff_visual is a fancy code visualizer using treemaps and source code thumbnails rendered through Cairo. It leverages static analysis of the code to give semantic feedback visually, which can help you understand the architecture of a project. Pfff_visual uses the pfff infrastructure, which is mainly an OCaml API to write static analysis, dynamic analysis, code visualizations, code navigations, or style-preserving source-to-source transformations such as refactorings on source code. For now, the effort is focused on PHP but there is preliminary support for JavaScript, C, C++, Java, SQL, and even TeX. There is also preliminary support for OCaml code so that the infrastructure can be used on the code of pfff itself.
