Dear colleagues, The deadline for our IEEE VIS workshop "3rd Workshop on the Creation, Curation, Critique and Conditioning of Principles and Guidelines in Visualization" has been moved to July 20, 2020 to accommodate for the extended paper and short paper deadlines at IEEE VIS. As the IEEE VIS conference will be held online this year, our workshop will be online, too. However, we do not yet know the details on timing and length of the workshop. We will post any updates on our website: https://nms.kcl.ac.uk/c4pgv <https://nms.kcl.ac.uk/c4pgv/> Best wishes, VisGuides: 3rd Workshop organizers ====================== Alfie Abdul Rahman, King's College London, UK Alexandra Diehl, University of Zurich, CH Benjamin Bach, University of Edinburgh, UK
