Create diagrams manually, or import your external data for analysis. Our automatic layout algorithms arrange even large data sets with just the press of a button.
I definitely like the usability and you can get started writing up a flowchart quick and easy. The included "layout" toolset kicks Visio to the curb with some amazingly cool organization tricks.

Testing setup:
1. Download as described here:
http://yed.yworks.com/support/qa/1134/c ... pplication
2. Unzip and run the .jar file
NOTE: I did not test it with PortableApps launcher, but I don't think that program prevents AppData writes so it's likely still not portable.
Status: not portable, writes settings to AppData\Roaming\yWorks

License: Open source, but with a very weird license. The portableapps link above goes into some detail here but this doesn't exactly inspire confidence. There's a non-distribution clause that sucks (what if they go out of business?) and the most annoying part as there's a bizzare "survival" clause:
"The Licensee may terminate this Agreement at any time by destroying all copies of the Software in possession."
