CSE 578 Data Visualization with complete
updated questions & answers
Data processing - answer user knows what he/she wants and has a
function to compute it
Querying - answer user knows what he or she wants and can describe it
Navigation - answer user knows what he or she wants and use cannot
describe it or locate it
Exploration - answer user doesn't know what he or she wants. Wants to
acquire new knowledge and reveal new facts
5 Types of Exploration Tools - answer 1. Analysis (identify common
patterns or outliers)
2. Comparison (quantify similarities/differences)
3. Aggregation (create groups and clusters)
4. Transformation (use a more convenient representation)
5. Visualization
3Vs - answer Volume, velocity, variety
,HMLE - answer High dimensional (lots of different things we want to
explore)
Multi modal (different ways needed to visualize it)
Inter-linked (data is linked, sometimes null, sometimes implicit)
Evolving (underlying patterns change)
INS - answer Imprecision
Noise
Sparsity
Cognition - answer The mental action of efficiently and effectively being
able to process information into thoughts, knowledge, and insights
Visualization - answer Graphically representing data to assist the
processing of information into knowledge, insights, and thoughts.
Uses exploratory data analysis to find trends and patterns in datasets.
, Main components of a sequence - answer starting point, ending point,
length
Data Deluge - answer A vast increase in the amount of data generated
by individuals and businesses.
Dynamic visualization - answer displays a single interactive visualization
of data
Features - answer vector representations of objects in a dataset
Schema - answer structure and properties of a data collection
Schemas enable retrieval of data for what? - answer Comparison,
indexing, query optimization, and query processing
qualitative color scheme - answer best for nominal data
What are Bertin's 7 visual variables? - answer 1. Position
2. Size
3. Shape
4. Rotation
