Come to the Vibrant Data PDX Hackathon! Saturday, June 2, 2012 from 8:30am–8pm

Vibrant Data Project - PDX HackathonImagine a world in which data becomes a personal asset that works on behalf of our personal interests and communities. Everyday, apps like yours could control how to send their data out into the world to circulate and bring back value to users. Certainly this would require a change in the way the world views data today, and in the infrastructure that enables it to flow freely while protected. This event is a first step in building that infrastructure for the benefit of all.

Consider the prospect of Facebook, Google, Amazon, LinkedIn and other data silos bidding against each other for what data you might provide. What kinds of data might be the most interesting? How could that value be enhanced? How could you collect it with minimal effort? How would your privacy be protected? What could you get in return?

At this event you’ll pick a particular type of personal data and build an app to show how its value as a personal asset can be enhanced. The app can be mobile, desktop, web or something else.

Global Open Data Visualization Contest

Visualizing.org, the global open data visualization platform created by Seed Media Group and GE, opened its World Water Day data visualization challenge this week in collaboration with Circle of Blue, the leading news organization reporting on global water challenges. The challenge calls on designers, data experts, and visualizers to tap into the world’s stream of water data to create visualizations specifically on the topic of urban water. The international contest offers a $5,000 cash prize to the winner and offers a chance for contestants to help solve urban water issues through data and design.

Google Group:

Ed Borasky started a Google group called pdx-visualization. As the name implies, it is a group for Portland-area people interested in languages and techniques for visualization of data. http://groups.google.com/group/pdx-visualization.

Innovation in Data Visualization Group on Flickr:

I’ve been collecting interesting data viz photos for a while now and posting them to Flickr. They’re all accessible on my Flickr account in this set. Most pictures contain descriptions and links to the viz sources. If you have any Flickr photos of data viz work you’ve done, or work your find innovative, be sure to add them to the group!

Using Netvizz and Gephi to analyze a Facebook network

Here’s what the output looks like: http://www.flickr.com/photos/49155467@N06/4583993987/sizes/o/

Made with My Online Social Network app for Facebook, and visualized with GUESS.

I get a “not found” error.

But when I try to run it myself, I get a “Not found” error.

Social Network Graph of Amber Case

TouchGraph Photos seems to have been discontinued.

There’s an excellent Slideshare presentation:
Facebook network analysis using Gephi

Following an announcement on Sept 30 2009, Nexus friend grapher shut down permanently on Oct 7 2009. Nexus generated over 500,000 friend graphs for 84,000 users. It was shut it down because it’s creators no longer had time to maintain or operate it.

The Nexus site suggested a few possible alternatives: Social Graph, TouchGraph Photos, NameGenWeb (data only), Friend Wheel, Facebook friends Constellation. For Twitter, MentionMap.

Only one of these works for Facebook, and that’s Friendwheel. Unlike the others, it doesn’t group users in a way that shows the social gravity between users.

I was able to find another alternative, My Online Social Network app on Facebook, visualized with GUESS.

It also doesn’t work. I was able to find Flickr photos of the output from owners, and I asked them what happened to their apps. No responses yet.

Netvizz

I found Netvizz, which generates GDF files for GUESS and Gephi. http://apps.facebook.com/netvizz/

This is the only thing close to working, but when I run it, I get:

netvizz v0.3
Fatal error: Uncaught exception ‘FacebookRestClientException’ with message ‘This API call could not be completed due to resource limits’ in /var/www/fbapi/netvizz/php/facebookapi_php5_restlib.php:3374 Stack trace: #0 /var/www/fbapi/netvizz/php/facebookapi_php5_restlib.php(1723): FacebookRestClient->call_method(‘facebook.users….’, Array) #1 /var/www/fbapi/netvizz/index.php(124): FacebookRestClient->users_getInfo(‘13467,13903,124…’, Array) #2 {main} thrown in /var/www/fbapi/netvizz/php/facebookapi_php5_restlib.php on line 3374

I checked the resource limitations, and it is built to handle networks of up to 4500 connections. I only have 900.

Then I found this:
Facebook Mutual Friend Network Visualization in Flash

The interface lets you see which of your friends know each other. At any given time it will show one of your friends as the selected node (in bold), and any mutual friends as additional nodes. Lines between nodes represent friendships. Clicking a node will select it and you and the new person’s mutual friends will appear. Finally, the colour of the circles represents gender for now: yellow is female, purple is male, and grey is unknown.

Guess what? It doesn’t work either.

Also, a lot of the source code became part of the Constellation Framework graph visualization library so the creator can’t release it. Although he mentioned on his blog that he was hoping to do another Facebook visualization using Framework and make the source for customizations available, nothing has shown up on his site.

Now what?

Here’s my question: does anyone know of any other solid ways to visualize Facebook network data? If not, is anyone interested in getting the Nexus code back up and running? It’s available and generates the best visualizations I’ve seen out there.

Nexus source code: Nexus-2009-10-14.tar.bz2 (see MUST-README.txt, DEPLOYMENT.txt files)

It’s written in Python and JavaScript, but the code quality is “PHP era” (no test coverage, tightly coupled, other problems). The site creators mention that it will take two days to get a Nexus instance running. If you do not know Python or cannot use a shell on Linux, it will not work for you.
