“SpaceNav lets your explore your tags represented as an inifinite 2D space. It will enable you to discover the relations between your tags, as well as recognize different patterns characterstics of certain grops of tags. In SpaceNav, tags are represented both as text (this is what you see when the applet starts) and as a small point encircled by an aurora (this is what you see when you clicked on a tag). The radius of the aurora represents the number of posts that were tagged using the tag. When a tag is clicked on (we say choosen), related tags will be laid out in circle around it.”Visit the website
