Roland,
this has the makings of what I call a "Game changer"
Excitedly looking forward,

Hi everyone,
this isn't quite ready for public consumption yet, but based on Mike
Bostock's really cool implementation of zoomable circular treemaps (on
bl.ocks.org), I've been working on a widget that can generate and
render diagrams like the following one:
<https://i.imgur.com/29Kqoa7.png>
(Screen recording <https://i.imgur.com/ncYVCu6.mp4> of the same
diagram in action).
The motivation behind this is to have dynamically generated diagrams
which can provide a "bird's eye view" on larger hierarchies of
tiddlers inside a TiddlyWiki.
The diagrams display hierarchies as layouts of nested circles. These
hierarchies are automatically discovered by recursively following TW
links or tags, starting from a root tiddler. Usually, leaf nodes in
circular treemaps are different in their size, which can be used to
visualize some tiddler properties, like a tiddler's character count,
or the number of links, number of backlinks, or number of tags each
tiddler has. The leaf node size can also be a uniform value for all
circles.
There are a few remaining problems, though. The diagrams currently
won't always update when a new tiddler is created and should show up,
but I think this can be fixed. Also, the tree builder should be a
reusable component, so instead of one plugin this should be split up
into two dependent plugins, one for the diagram widget, and one for
the tree builder. Unfortunately, there's also a small amount of code
that is common to both components, and I have no good idea how to not
duplicate these parts.
If anyone feels inclined to try this out, here's an expiring link:
http://viewtransform.net/d3trees/d3trees-preview.html. I'll leave this
up for a few days.
Best wishes,
-- Roland
