This year in the context of the BigVis 2020, we have invited 14 distinguished scientists from academia and industry and diverse communities (i.e., Information Visualization, Human-Computer Interaction, Machine Learning, Data management & Mining, and Computer Graphics) to provide their insights regarding the challenges and the applications they find more interesting in coming years, related to Big data visualization and analytics.

Particularly, each scientist summarizes his thoughts regarding the following two aspects:
   − the top future research challenges in Big Data visualization and analytics
   − the top emerging applications in the context of Big Data visualization and analytics

The list of the scientists follows:
Gennady Andrienko Fraunhofer, Germany
Natalia AndrienkoFraunhofer, Germany
Steven Drucker Microsoft Research
Jean-Daniel Fekete Inria, France
Danyel Fisher
Stratos Idraios Harvard, USA
Tim Kraska MIT, USA
Guoliang Li Tsinghua University, China

Jock D. Mackinlay Tableau
Antti OulasvirtaAalto University, Finland
Tobias Schreck Graz University of Technology, Austria
Heidrun Schumann University of Southern Denmark, Denmark
Michael Stonebraker MIT, USA

The report is going to be available in the BigVis proceedings and discussed in the BigVis opening session.
