 								<h2>Message passing graph</h2>
 								<p>In Erlang-based systems processes share data through message passing.
                     If certain processes receive more messages than they can handle,
                     their inbox queue starts growing. Over time it can lead to bottlenecks.
                     The graph visualises which processes communicate extensively
-                    and highlights them in red, so you know which ones to click and inspect.
-                    You can even put on a pair of 3D glasses
-                    and admire the beauty of complex systems visualisations.
