Narrative visualisations : telling stories with data - Coggle Diagram
Narrative visualisations : telling stories with data
Intro
an emerging class of visualizations attempts to combine narratives with interactive graphics.
story-telling, technical and staging skills
Data stories (interactivity) =/= traditional storytelling (tightly controlled progression)
Narrative visualizations may incorporate a variety of media : text, images, videos
interactivity allows it to rely as much on the reader as on the author
allows to communicate quickly complex content
Visual narratives
Clear starting point
Visual salience is influenced by
color
size
orientation
reading order
spatial proximity, containment or connexion
vectorial reference
transitions (object consistancy and de-emphasization on secondary details)
Design Space Analysis
Genres
Magazine style
annotated chart
partitioned poster
flow chart
comic strip
slide show
film/video animation
genres are not exclusive : they can function like building blocks, combining to produce more complex visual genres
Visual narrative tactics
: visual devices that assist and facilitate the narrative
Highlighting : help to direct the viewers attention to particular elements in the display
Visual structuring
: mecanism that communicate the overall structure of the narrative to the viewer and allow him to identify his position within the larger organization of the visualization
transition guidance : moving within or between visual scenes without disorienting the viewer
Narrative structure
Author-driven
Linear ordering of scenes
heavy messaging
no interactivity
goals
efficient communication
Reader-driven
no prescribed ordering
no messaging
free interactivity
goals
data diagnostics
pattern discovery
hypothesis formation
types of narrative structures
Martini Glass Structure
: author driven approach, and when it's complete the visualization opens up to a reader-driven stage where the user is free to interactively explore the data
interactive slideshow
: rigid structure but it may incorporate interaction in each slides. Good for complex narratives
Drill-Down story
: general theme and freedom to chose among particular instances of that theme to reveal additional details and backstories
Clustering of different ordening structures
consistency of interaction design
under-utilization of narrative messaging
