Prerequisite Knowledge

The session would be valuable for data scientists and data analysts involved in conducting exploratory data analysis (EDA) with large multi-dimensional datasets. Exposure and prior experience with EDA in any data tools like Excel, Tableau, R, or Python would be helpful.

Description

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

Standard 2D/3D approaches

  • Aesthetics e.g. color, size, shape
  • Small multiples e.g. trellis/facets
  • Matrix 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 multidimensional data.

Interactive Approaches

  • Navigation – pan, zoom, scale, rotate
  • Selection and annotation
  • Filtering – highlighting, brushing, and linking
  • Layering
  • Dynamic queries
