Data visualization or data visualisation is viewed by many disciplines as a modern equivalent of visual communication. It is not owned by any one field, but rather finds interpretation across many (e.g. it is viewed as a modern branch of descriptive statistics by some, but also as a grounded theory development tool by others). It involves the creation and study of the visual representation of data, meaning “information that has been abstracted in some schematic form, including attributes or variables for the units of information”.

An example of a Day/Hour Heatmap showing concurrent user sessions over time in a development environment. It was generated with WP-D3 v2.1.1 and adapted from http://figurebelow.com/d3/wp-d3-and-day-hour-heatmap/. [d3-source canvas="wpd3-723-0"] [print-me]
This example pie chart shows the relative size of various age groups. It was adapted to work in WP-D3 v. 2.1.1 from the original located at http://figurebelow.com/2013/03/13/wp-d3-tutorial-adding-d3-snippet-into-a-wordpress-post/ [d3-source canvas="wpd3-715-0"] [print-me]
This demo chart contains the stock and Bollinger Bands (red) of Ford stocks (blue) between 1-Feb-2013 and 31-Jan-2014 and was adapted from the original located at http://figurebelow.com/d3/short-tutorial-into-wp-d3-v2/. [d3-source canvas="wpd3-709-0"] [print-me]
A box-and-whisker plot uses simple glyphs that summarize a quantitative distribution with five standard statistics: the smallest value, lower quartile, median, upper quartile, and largest value. This summary approach allows the viewer to easily recognize differences between distributions.
As Mike Bostock explained, this simple force-directed graph shows character co-occurence in Les Misérables. It is a physical simulation of charged particles and springs that places related characters in closer proximity, while unrelated characters are farther apart.
This simple bar chart originally by Mike Bostock is constructed from a TSV file storing the frequency of letters in the English language. The chart uses the following D3 features: d3.tsv – loads and parses data from a tab separated file d3.format – format percentages d3.scale.ordinal – x-position encoding d3.scale.linear – y-position encoding d3.max -[...]

Switch between stacked and grouped layouts using sequenced transitions! Animations preserve object constancy and allow the user to follow the data across views. Animation design by Heer and Robertson. Colors and data generation inspired by Byron and Wattenberg.
Designed by Stephen Few, a bullet chart “provides a rich display of data in a small space.” A variation on a bar chart, bullet charts compare a given quantitative measure (such as profit or revenue) against qualitative ranges (e.g., poor, satisfactory, good) and related markers (e.g., the same measure a year ago).
