Tag clouds are very useful to visualize the most frequently used tags on a website, e.g. a blog. This is done by steering attention through emphasized words whose font size, color or position stands out. But nothing can be found out about temporal relation of a tag’s posts. For me this became evidently on my own tag cloud (see left) which still rates ‘Lima‘ at the leading position whereas the related articles are more then three years old.
More unfortunately is the missing relation to other tags. While one tag is really highlighted the user can not figure out anything about related tags who may appear concurrently.
In order to push semantic visualization I am going to introduce TagArcs as meaningful and eye catching way to outline relationships between tags and posts.
