[okfn-labs] request for help on usability / visualisation

[Gregor Aisch]

And not to forget, there's a free online course about social network analysis (and visualization), which probably is exactly what you need to get more out of that data.

There are 21k students enrolled in the course (including me), but there's still some place left in the auditorium. Judging from the first week (the course has just begun) the lectures are really great.

I think you should participate as well. Again, it's free.

Best,
Gregor

If yes, there might not be *that* many, to include them all in one visualization. If it's less than 200-300 hundreds, it should work. How about showing which persons are related to similar companies?

I was wondering if OKF Labs could help the project to improve and become even better by providing feedback and recommendations on the usability and the visualization? This does not include coding or design and have to be time consuming. I think a short expert review and skype session would already be very helpful.
