From Japan, but working in English, iroha Note takes a textual approach to visualization – or a visual approach to text notes (take your pick).
Its free version feels rather like clustering with Post-it notes, but adds the capability to freely associate notes using visible but subtle linking lines. In an optional box on the left, an outline appears to show the macro-level structure.
The paid-for version, iroha Note+, adds in the ability to paste images into the notes (called leaves), export images and print.
This is desktop software, running in Adobe Air, that can be used on Windows, Mac and Linux.
I found a few operational glitches when using it, but nothing I couldn’t work around. It is under active development, so we can expect these to be fixed.
