Social network - Visualization of relationships modules

Visualization modules

I will visualize in 2d space graphs various relations of social network data:

1. relationships between users (friends, fans, enemies... and groups of these relations)
2. relationships between artworks ("people who like this artwork also like these:" -> similar favorite artworks list)
3. activity of users on the timeline
   platforms: PHP or Flash (i have to make a research which one is more suitable, flash seems to be more attractive, but i don't have any experience with flash & database yet)
   

1) relationships between users

• (basic) display active users (in ring) with connections (lines) of "friends" and "a fan of" between themlines can have different width of stroke or color or both, depending on "relative value" of relationship
• display all users (in 2d space graph) so that FRIENDS ARE CLOSER to each other
• display gallery as clusters - GROUPS OF FRIENDS
• display gallery as groups of users that are hostile (show TENSIONS, hostility between gallery users)(bonus: compare tensions from previous days, highlight areas that became worse)

2) relationships between artworks

• display related artworks to current artwork
• display 2d graph of artworks (artwork thumbnail = node), in which i can move by clicking on related artworks

3) activity of users on the timeline

• display a timeline on axis x, and (one) USER'S ACTIONS on axis y - more actions per day will display at increasing y-coordinate
• display a timeline on axis x, and ALL ACTIVE USERS from that day on axis y,user names serve as links to graph number 1 (user's actions)

I'll start with basic relationships between users and then I'll focus on relationships of artworks. This is the most useful module for the users (the rest is more useful for the administrator).
