Conference «Untangling the hairball: Visual analytics and information visualization» (John Alexis Guerra Gómez)

Many times a data analysis task can be represented as a collection of connections or relationships between entities, such as partnerships, business relationships, or simple co-occurrences. In information visualization, we can model and represent those relationships as networks, and we usually represent them using force directed node link diagrams. However, despite their promise, network visualizations with a few hundred nodes can quickly turn into a tangled hairball.

Lecturer: John Alexis Guerra Gómez, researcher at U. de los Andes, where he investigates novel information visualization techniques for photos, networks and trees. He is also a lecturer at U. of California, Berkeley

Date and time: Tuesday 18 April 2017, 16:00-17:00

Venue: Paraninfo Juan B. Gómez at edificio Julio Garavito Armero, Facultad de Ingeniería, Universidad Nacional de Colombia sede Bogotá (Carrera 30 45-03, building 401, see map)
