179 Goal: simplify/speed up understanding the computer program code by
180 automatically visualizing its structure.
184 JavaInspect is a Java library that you can embed into your Java
185 project with a few lines of Maven configuration and then visualize any
186 part of your Java program structure with few simple JavaInspect API
187 calls at application runtime.
191 JavaInspect uses Java reflection to discover class relations and
192 structure and produces GraphViz dot file that describes your
193 application. Then launches GraphViz to generate bitmap graph in PNG
194 format on your Desktop directory.

201 <div class="outline-text-2" id="text-2">
203 This is simple utility, quickly written. Tested on GNU Linux (can be
204 relatively simply ported to other operating systems too). So far I
205 used it for my own needs. There might be bugs and missing
206 features. Feedback and code contributions are welcome.
