Objective

To understand techniques to effectively visualise multi dimensional data to aid exploratory data analysis.

Description

Even though exploring data visually is an integral part of the data analytic pipeline, we struggle to visually explore data once the number of dimensions go beyond three. This talk will focus on showcasing techniques to visually explore multi dimensional data (p > 3). The aim would be show examples of each of following techniques, potentially using one exemplar dataset.

Standard 2D/3D Approaches

  • Aesthetics e.g. Color, Size, Shape
  • Small Multiples e.g. Trellis / Facets
  • Matrices Views e.g. SPLOMs
  • 3D Scatterplot

Geometric Transformation Approaches

  • Alternate Coordinates e.g. Parallel, Star
  • Projections e.g. Dimensionality Reduction
  • Tablelens

Glyph based Approaches

  • Star glyphs
  • Stick Figures

Pixel based Approaches

  • Pixel bar charts
  • Space filling curves

Stacked based Approaches

  • Dimensional Stacking
  • Hierarchical Axis
  • Treemaps

The talk will also explore the role of interaction approaches to enhance our ability to visually explore the multi dimensional data.

Interactive Approaches

  • Navigation - Pan, Zoom, Scale, Rotate
  • Selection & Annotation
  • Filtering - Highlighting, Brushing and Linking
  • Layering
  • Dynamic Queries
