Query: Studying Visualization Guidelines According to Grounded Theory   Visualization guidelines, if defined properly, are invaluable to both
practical applications and the theoretical foundation of visualization. In this
paper, we present a collection of research activities for studying
visualization guidelines according to Grounded Theory (GT). We used the
discourses at VisGuides, which is an online discussion forum for visualization
guidelines, as the main data source for enabling data-driven research processes
as advocated by the grounded theory methodology. We devised a categorization
scheme focusing on observing how visualization guidelines were featured in
different threads and posts at VisGuides, and coded all 248 posts between
September 27, 2017 (when VisGuides was first launched) and March 13, 2019. To
complement manual categorization and coding, we used text analysis and
visualization to help reveal patterns that may have been missed by the manual
effort and summary statistics. To facilitate theoretical sampling and negative
case analysis, we made an in-depth analysis of the 148 posts (with both
questions and replies) related to a student assignment of a visualization
course. Inspired by two discussion threads at VisGuides, we conducted two
controlled empirical studies to collect further data to validate specific
visualization guidelines. Through these activities guided by grounded theory,
we have obtained some new findings about visualization guidelines.
