Update 2017-08-05: link to org-mind-map

Yesterday, I wrote my first Python 3 script which is a helper script
to visualize sizes (number of lines) of Org-mode headings: [[https://github.com/novoid/org-du][org-du]]

I borrowed a different workflow from two GNU tools: Usually, the
output of [[https://github.com/novoid/org-du/blob/master/du][du]] (disk usage) is piped into [[https://directory.fsf.org/wiki/XDU][xdu]] to visualize disk usage of
directories. =org-du= mimics the output format of =du= in order to be
able to use =xdu= to do the visualizing and navigational part.

Applying the script on [[https://github.com/novoid/org-du/blob/master/README.org][the README.org file]] and piping the output into
=xdu= looks like this:

: org-du.py README.org | xdu

#+BEGIN_EXPORT html
<img src="https://github.com/novoid/org-du/raw/master/xdu-screenshot.png" />
#+END_EXPORT

You can navigate through the output via mouse, navigate back in the
tree by clicking the leftmost column, and quit via =q=.

The script also accepts multiple Org-mode files as arguments. This
way, you can get a brief overview of all of your Org data.

=org-du= works on any platform which runs Python 3. However, =xdu= is
available on UNIX/GNU/Linux only. You can do the =org-du= part via
=org-du my-file.org > my-org-du-output.log= on a Windows host, copy
the result file to a GNU/Linux host and do the visualization part with
=xdu < my-org-du-output.log= as well. This way, you can separate the
data analysis and the data visualization part.

You can install =org-du= via =sudo pip install org-du= or clone from https://github.com/novoid/org-du

Have fun with this tool!

Update 2017-08-05: if you need to visualize the structure of your
Org-mode file, you could check out [[https://github.com/theodorewiles/org-mind-map][org-mind-map]].
