Dagstuhl's Impact: Documents available


For the majority of human existence, the visual language has been successfully used to communicate complex ideas that span across borders of knowledge, experience, age, gender, culture, and time. These aspects also make it an effective form of expressing workflows in scientific data analysis as well as the communication of scientific discoveries to broad audiences. The Dagstuhl Seminar 19262 brought together researchers from computer science, content producers, learning and communication experts, and domain experts from astronomy and astrophysics to define the emerging field of interactive visualization of space exploration and astronomy, referred to as Astrographics. This seminar played an important role in the ongoing process of removing the clear division between using visualization to enable scientific discoveries by subject-matter experts (exploratory visualization) and using visual representations to explain and communicate the results of such exploratory science to a greater, general audience (explanatory visualization). Designing the available visualization tools to serve both roles at the same time increases the overlap between these two aspects of visualization and allows scientists to better explain their findings and, at the same time, enables the general public to use similar tools for their own, guided, discovery and actively participate in the scientific process. The field of astronomy and astrophysics has been at the forefront of this process since the beginning as it is a primary example of a domain in which exploratory and explanatory visualizations have served important but distinct roles. For this reason, astrographics was chosen as the domain in which to explore the challenges and opportunities that arise when combining exploratory and explanatory techniques. The bulk of work in this seminar occurred in focussed break-out sessions that reported their findings back to the group and opened up the topics for joint discussions. Topics of these break-out sessions included discussions on better integration of software tools, improvements of analysis tools, preparing astrographics software packages to improve the quality of public presentations, the ability of sharing presentations both in spatially distant locations as well as saving them for later playback. Finally, there was a working group to work on a decadal white paper for astronomy [1].
