4- Fidg't
Fidg't
is a desktop application that allows you to view your social networks
tagging habits. You can check out what kind of music your network is
into, or what kind of photos they are sharing. Their 'Visualizer' tool
shows how your network compares to a random sampling of the networks of
other Fidg't users, letting you see how your network stacks up to
others? To use Fidg't, you interface with the Visualizer through Flickr
and LastFM tags, using any tag to create what they call a "Magnet."
Once a Tag Magnet is created, members of the network will gravitate
towards it if they have photos or music with that same Tag.

5- Digg's Visualization
Digg.com
has some very unique web-based visualization tools that basically take
all of the incoming Diggs entering the social bookmarking site and
slices and dices those submissions in various ways.
Digg's BigSpy
positions stories at the top of the screen AS they are dugg.
Consequently a popular story with the most Diggs will be seen at the
top of the page, until newer and more popular stories take their place.
Digg's Stack
shows diggs in real-time, with diggs falling from the top of the
screen. As stories get more Diggs, they appear in brighter colors.
Digg's Swarm shows
the stories surrounded by circles. With more popular entries, Diggers
will swarm around stories allowing them to grow larger and appear
brighter.
Digg's Pics
is one of the latest tools that tracks the activity of images on the
site with a slider mechanism that slides images into view from the left
to the right.
Digg's Arc displays stories, topics and containers wrapped around a sphere, whereby the more Diggs, the greater the size of the arc.

6- Twitter's Visualization
When
you find the Twitterstream getting a little boring at times, consider
some of the clever APIs that have been developed to entertain us by
giving us a fun-way visual view of Twitterville.
Twittearth is
is a 3D model of tweets from around the globe. It pulls in tweets and
visualizes them in relationship to Earth, even taking into account the
parts of the world that are experiencing daylight and nightfall. You
can also follow Twittearth on Twitter (@twittearth)

Twittervision
is another geographic visualization of tweets coming in from all four
points of the globe. It features both 2D and 3D visualization and
integrates with Facebook. Users can publish their specific locations
and statuses using this API.

Twitter Stream Graphs tracks
keywords and what is trending literally in the Twitterstream. Instead
of loading bar charts or line items, it uses streams to display words
and tags and can visualize the top keywords of any individual tweeter. Jeff Clark who developed this tool has also developed Twitter Spectrum and TwitArcs.

This GoodMorning
video is an overview of a Twitter visualization tool that shows about
11,000 "good morning" tweets from around the globe over a 24 hour
period, between August 20th and 21st.
7- Facebook's Visualization
Visual
representation of the Facebook network offer limitless possibilities.
Some of these visualization come with tools allowing you to create some
pretty nifty Facebook visualizations of your own.
Facebook Friend Wheel

This application is also available to graph your Twitter followers.
Here is a display of my Facebook Friend Wheel

TouchGraph Facebook Browser
is a Java based application that lets you see the connections between
your Facebook friends, their photos and their locations. Interactive
tags and friend’s names in the photos are clickable where you can click
on a friend’s name to see them in another photograph. Here's a snapshot

Facebook & Twitter
Since social networks are all about being social, the visualizations on Twitter and Facebook are a unique opportunity to acknowledge your friends and followers to show your appreciation of them for being part and parcel of your social networks. It's also a means to communicate to others just how active you are in the social media space. Numbers are one thing, but what is it that we say about "one picture being worth a thousand words."
