Graphical Representation and Visualization Techniques

Flashcards covering key concepts in graphical representation and visualization techniques discussed in the lecture.

Facets

A technique that allows a third dimension to be introduced in data visualization, adhering to Tufte's theories of graphical excellence.

Faceting Variable

A categorical variable used in faceting to create mini plots that share the same structure, axes, and scales.

Facet-Whap

A faceting technique ideal for single variables, showing only plots/data.

Facet-Quid

A faceting technique ideal for multiple variables, displaying all possible combinations of data.

Choropleth

A method that shows values of a quantitative variable, with color that may vary continuously or in categories.

Unique Values

A visualization technique using color to show the value of a categorical variable, typically for variables without ordering.

Dot One-to-One

A map where dots represent actual data points at their locations, encoding info about specific observations.

Dot Density

A map of geographic or administrative areas where dots and color represent quantities, with dots being randomly distributed.

Dasymetric Dot Density

An extension of dot density where dots are placed in regions where data is more likely to be found, requiring ancillary data about population densities.

Cartogram

A map where the size of areas is distorted to represent quantities, requiring ancillary data for quantification.

Graphical Integrity

A principle that maintains the accurate representation of quantities, emphasizing that data variation should not be confused with design variation.
