Contributions Introduction Data Exploration without Specification - PowerPoint PPT Presentation

Visualization by Demonstration: An Interaction Paradigm for Visual Data Exploration Contributions Introduction Data Exploration without Specification B. Saket, H. Kim, E. T. Brown and A. Endert IEEE Transactions on Visualization and Computer Graphics Use demonstrations to generate: - visualizations techniques - mappings Dilan Ustek 7 March 2017 - parameters Visualization by Demonstration Video https://www.youtube.com/watch?v=JFdStB0nYRs 1. Does not require users to specify vis techniques Design Guidelines 2. Extracts vis mappings and parameters VisExemplar 1. Support direct manipulation 2. Balance human/system workload 1. Support direct manipulation 2. Balance human/system workload 3. Enable user interactions to drive transformations 4. Enhance interpretability of recommendations 3. Enable user interactions to drive transformations 4. Enhance interpretability of recommendations WHAT Table WHY Explore , compare, and summarize Task Example Scatterplots and bar charts HOW Manipulation: resize, recolor, reposition SCALE Hundreds or Thousands

Tradeoff between Transforming to vis techniques with 1 2 3 4 flexibility of vis-by-demonstration Other vis techniques No sophisticated analytic operations different graphical encodings vs. the loss of formality Critique 1. No validation 2. Need to keep track of favorite points -> makes comparison hard 3. Cannot set axis to a certain attribute Exploring methods of presenting 5 6 4. Great start to the exploration problem. Consistency in visual mappings Thank you! Dilan Ustek recommendations in visualizations
