I just finished reading an early release of Doug Finke's upcoming
O'Reilly book 'Windows PowerShell for Developers'
( Windows PowerShell for Developers [Book] )
which I thoroughly enjoyed. In Chapter 9, 'Writing Little languages in
PowerShell',
he has a section on GraphViz ( http://www.graphviz.org/ - drawing graphs
since before
you were born 
and how to write DOT files from PowerShell. Wouldn't it be
nice
to have a cmdlet in PSH5X that creates a quick visual of an HDF5 drive?
vi Show-H5Drive.ps1 ... (Have a look at the source!)
The latest version of PSH5X includes the Show-H5Drive cmdlet which
conveys the idea. (Improve it for your own purpose!)
The attached PNG was created via
Show-H5Drive sample | & 'C:\Program Files (x86)\Graphviz 2.28\bin\dot.exe'
-Tpng -o sample.png
or SVG
Show-H5Drive h5 | & 'C:\Program Files (x86)\Graphviz 2.28\bin\dot.exe' -Tsvg
-o h5.svg
or ...
It shows the (multi-)graph structure of the sample file from the PSH5X
tutorial.
The edge labels are link names and the node labels are of the form:
{item type abbreviation}_{address in the HDF5 file}
For example, G_1293 is a group object at address 1293.
'sample.gv' shows the output generated by Show-H5Drive. Check it out for
yourself!
