TiddlyMap exclude specific node/tag

I’ve imported my bookmark archives from Pinboard.in into TW, ~3.3k tiddlers. To group all bookmark tiddlers, I’ve given them a _pbb tag, in addition to their “normal” tags like for example music, movie etc.

I’m trying TiddlyMap to see if it helps visualizing connections between bookmarks and their tags. My problem is that because the _pbb tag is related to so many tiddlers, any time it tries to visualize it as a node, it crawls to a stop. Which is 100% understandable.

How can I exclude this tag from the visualization? I’ve tried updating the Node filter in the View Configuration to the following but it doesn’t work:

[[!tag[_pbb]]+field:title{$:/temp/tmap/currentTiddler}]

I don’t know anything about TiddlyMap, but the filter doesn’t look right. It’s currently looking for every tiddler that does not have the _pbb tag (so it’s leaving out all of your bookmarked tiddlers, if they all have that tag) and that also *does have the title determined here: {$:/temp/tmap/currentTiddler}

I don’t know what your bookmark tiddlers have in common besides their _pbb tag, but whatever that is, you want to catch all of those tiddlers, and then leave out your _pbb tiddler (but not all the things tagged by it!). Something like:

music movie image [tag[music]] tag[movie]] [tag[image]] -_pbb

If I were you, I probably wouldn’t tag all your bookmarks themselves with _pbb, but would instead tag each of your categories with that (or would use some other field value or other effective list condition to catch all the bookmarks). It’s easy enough then to show a list of all things with tags that are in turn tagged with _pbb…

Sorry to be replying in haste. I hope this gets you a step closer to what you need.
