Information Visualization (infovis) has, for years, been limited to small data: a typical
infovis application will work well with up-to 1000 items/records, a few can scale to 100,000 items,
and very few have been able to deal with millions of items. Billions are seldom mentioned in the
infovis literature. In contrast, the research fields of machine learning and databases are
sometimes dealing with datasets of several billions of items, and the numbers are growing.
There are legitimate reasons why it takes time for infovis to start catching-up with these large
numbers, and some work such as Lins et al. Nanocubes (http://www.nanocubes.net/) and Liu et al. imMens (http://idl.cs.washington.edu/papers/immens),
have started to show possible routes to scalability. However, they both rely on either pre-computed
aggregations that need hours to compute for large datasets, or on a highly parallel infrastructure
performing aggregations on the fly. In my talk, I will explain why we need more flexible solutions
and present a new workflow architecture called ProgressiVis, to achieve progressive computations
and visualization over massive datasets in a generic way.
Jean-Daniel Fekete is Senior Research Scientist (DR1) at INRIA, the French National Research
Institute in Computer Science. He received his PhD in Computer Science in 1996 from Université
Paris-Sud. From 1997 to 2001, he joined the Graphic Design group at the Ecole des Mines de Nantes
that he led from 2000 to 2001. He was then invited to join the Human-Computer Interaction
Laboratory at the University of Maryland in the USA for one year. During 2015, he was on Sabbatical
at NYU and Harvard.
He was recruited by INRIA in 2002 as a confirmed researcher and became Senior Research Scientist
in 2006. He is the Scientific Leader of the INRIA Project Team AVIZ (see
www.aviz.fr) that he founded in 2007 and that is well known
worldwide in the domains of visualization and human-computer interaction. His main research areas
are Visual Analytics, Information Visualization and Human Computer Interaction.
He is currently the chair of the IEEE Information Visualization Conference Steering Committee,
member of the IEEE VIS Executive Committee, member of the EuroVis Steering Committee, and member of
the Eurographics publication board. He is also an ACM Distinguished Speaker. He was the General
Chair of the IEEE VIS Conference in 2014.
