What are Multidimensional Data Visualizations?

There are two categories of Multidimensional  Visualizations.  The first looks at category proportions; or category counts.  The second examines the relationships between the variables.

Examples of visualizations that show category proportions or counts: pie chart, Wordles, bar chart, histogram, rank plot, tree map

Examples of visualizations that show relationships between variables: scatter plot, line chart, step chart, area chart, heat map, matrices, parallel coordinates/sets, radar/spider chart, box and whisper plots, mosaic display, waterfall chart, pixel bar chart, tabular comparison of charts
