Is there an alternative to Microsoft Office Visio?
Are there any alternatives to Microsoft Office Visio for Ubuntu?
I especially like yEd.
DIA is unusable in comparison. I still wonder how I managed to document my Bachelor's Thesis using it. Try aligning objects in DIA, try creating any diagram so that it doesn't look like it was done in 3 minutes.
I like LibreOffice Draw, its not as colorful as Visio, but works for me.
