       Massif  Visualizer  is  a  tool  that  visualizes  massif data. You run your application in Valgrind with
       --tool=massif and then open the generated massif.out.%pid in the visualizer.  Gzip  or  Bzip2  compressed
       massif files can also be opened transparently.

       The application consists of three parts:

       TheOverviewChart

       The first thing you'll notice is a nice chart that displays the same as e.g.  ms_print does in Ascii-Art:
       total memory consumption over time.

       Massif-Visualizer  goes beyond that by additionally showing the top most cost-intensive locations in your
       code as a stacked graph below the total cost.  The graph also reacts on user-interaction.

       This view you can use for:

       • checking whether your application has memory leaks

       • finding expensive peaks

       • finding locations that significantly contribute to the overall memory consumption of your application

       TheSnapshotDataTree

       Directly next to the above chart, you'll see a tree with all of the  massif  data.  The  tree  items  are
       colored  depending  on  their  cost,  with  red  opaque  being  the  most  interesting  (peak)  elements.
       Green/transparent items are negligible and don't add significant cost to your application.

       You can also search the tree and when you select something in it, the snapshot gets  highlighted  in  the
       overview chart and the call graph gets updated.

       TheCallGraphforDetailedSnapshots

       Massif  generates  a  few  detailed  snapshots  that  essentially make up the tree. If you want to get an
       overview in a more comfortable way than the simple tree view, switch over to the  detailed  snapshot  tab
       and  see  the  tree  visualized  as  a call graph. Zoom in, zoom out, use the birds eye view and see what
       contributes to a given snapshot. Note that function calls with the same memory cost are grouped to easily
       find the interesting parts.
