CSE 578 Exam 1 Verified Questions And Answers
With Latest Study Tests
What is external representation in data visualization? ANS The visual display of data on a screen or
physical medium.
What are examples of external representation? ANS Graph, chart, or map.
Limits of visualization ANS Computational, Human, Display
Four levels of validation ANS Domain situation, Data/task abstraction, Idiom, Algorithm
What QUESTION do we ask to figure out the Domain situation? ANS Who are the target users?
What QUESTION do we ask to figure out the Data abstraction? ANS What is shown?
What QUESTION do we ask to figure out the Task abstraction? ANS Why is the user looking at it?
What QUESTION do we ask to figure out the Idiom? ANS How is it shown?
Visual encoding ANS how to draw
Algorithm ANS Efficient computation
Nested model: Four levels of validation - CHART ANS domain -> abstraction -> idiom -> algorithm
Domain Abstraction : Main Idea ANS Want to define WHO will be reading your story, what is there
experience level with the topic?
Task abstraction: Main Idea ANS Involves defining WHAT information the reader needs from a story.
,What would a TASK ABSTRACTION for students/novice readers be. ANS Need an introductory and
well-thought-out story.
What would a TASK ABSTRACTION for Executive type readers be. ANS Need the conclusion and
important takeaways.
Narrative visualization ANS Combining (static or interactive) graphics with narration
Exploratory Aspects of Visualization ANS using visuals to discover patterns and insights within data when
you are still unsure about the key relationships
Explanatory Aspects of Visualization ANS using visuals to clearly communicate specific findings and
conclusions from the data to an audience
Narrative structuring ANS Non-visual techniques to assist and facilitate the narrative
Ordering in Narrative structuring ANS the "path" through the story
Types of Ordering in Narrative structuring ANS Linear, user-directed, random
Interactivity in Narrative structuring ANS How the viewer can manipulate visualizations
Types of Interactivity in Narrative structuring ANS -Hover highlighting/tooltips, filtering, search,
navigation buttons
-generally constrained in narrative settings
Messaging in Narrative structuring ANS accompanying words
Types of Messaging in Narrative structuring ANS Voiceover, captions, headlines, annotations,
accompanying article text, introductory and summary text
, Scrolljacking ANS unexpected scrolling behavior
Scrollytelling ANS Navigate a page/story by scrolling up/downactivating content based on scroll position
Scrollytelling Pros ANS Familiar and intuitive, works in browsers
Linear navigation (usually up or down) is simple
Scrollytelling Cons ANS Full screen mode may lack affordances
Scrolljacking (unexpected scrolling behavior)
What does 'Author Driven' mean? ANS The creator of the content strictly controls the narrative.
How does an Author Driven narrative present information? ANS In a linear path with minimal
interactivity.
What does 'Reader Driven' mean? ANS allows the audience to explore the data at their own pace through
interactive features, choosing which aspects to focus on and essentially driving the story themselves
How does an Reader Driven narrative present information? ANS interactive features and essentially
driving the story themselves
Biasing ANS encouraging one outcome over another.
Framing effects ANS small changes in how an issue is presented result insignificant changes in
interpretation
Definition of Omission ANS Deciding what NOT to explicitly show or explain
Definition of Simplification ANS Aggregate, filter, or derive simpler, less complex data to show
