Data Visualization & Information Aesthetics

Popularized in the "Table Lens" project from Xerox PARC [Rao and Card, 1994], these resemble series of bar graphs that can be sorted independently.…

A table arranges data using grids (rows and columns). It is sometimes called a matrix, a data table or a data grid. It is one of the most commonly and widely used data visualization types. A Little History Spreadsheets (interactive data table applications) first came about in the late 70's.…

IntroductionPhysical mapping is a visualization displaying a precise relative positioning of physical elements to each other in space. Physical elements can represent landforms and terrain, but also imaginary boundaries and measurement systems like borders, zip codes, or longitude and latitude. The physical map is a dynamic form of visualization, lending…

Permutation matrices are sortable charts used to explore patterns and correlations in multi-dimensional re-orderable data. Jacques Bertin knew that interaction is at the heart of exploring hidden relationships in data. Before modern computers existed, Bertin constructed physical wooden matrices (called "Dominos") to explore data. The re-orderable matrices were made through…

Though the tree and the graph are related, they are not equivalent. Let's get a sense of some history and background. Both the tree and the graph are non-linear data structures, the main difference as seen below in Fig. 1 is that a tree (on the left*) follows hierarchically ordered…

Definition A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.In a box plot, we draw a box from the first quartile to the third quartile. A…

Intro to Tree MapsTree maps usually represent a hierarchical structure of a large amount of data in the form of the size of rectangles and color scale. It provides a clear view of the complexity of the data and the comparison among different types of data. However, it is not…

Heat maps are a type of visualization to show data density. They are particularly helpful when you have a lot of (e.g., tens of thousands of) data points and are mainly interested in their overall distribution. Technically, in a heat map, data points are aggregated locally and mapped to…

What’s scatter plot?Scatter plot is a type of diagram using Cartesian coordinates to display values for typically two variables for a set of data. It shows the correlation between variables. In two dimensions, it uses dots to represent the values obtained for two different variables, one plotted along…

What is Visual Diff: A Visual Diff compares and shows differences between rendered text documents. It is definetely useful when we want to keep the progress updated and track the certain changes been made. Some typical examples exists in linux system. Imagine that as a programmer, It is pretty common…

Sometimes it is also be called "3D heat map".  It usually be used for geo-related information lay out. Except the 2D map, it can also holding at least two kinds of informations, which can be presented by heights and colors.Rubber Sheet also usually be compared with isosurfaces, which have…

Description Arc diagrams are two dimensional informative network graph. It constitutes of two elements i.e. node and links. 1.1. Nodes Nodes represents the entities of the data. It is presented in a single line usually on a horizontal axis. Further information or details can be translated into the…

Is a graphical technique that can simultaneously explore the associations between thousands of subjects, variables, and their interactions, without needing to first reduce the dimensions of the data. Matrix visualization involves permuting the rows and columns of the raw data matrix using suitable seriation (reordering) algorithms, together with the corresponding…

About The chernoff faces method (invented by Hermann Chernoff in 1973) can be used to visualize multi-dimensional values. Thus instead of a visualizing a single value and its expressions, multiple different values can be displayed and/or researched. As the name implies, the method uses the human face and its…

Choropleth maps depict variations in spatial data by shading geographic areas according to a statistical measure. They make use of a gradient of hue, value, and texture, and often follow pre-defined geographic boundaries such as census tracts, cities, states, or countries. ValuesThe choropleth map can represent various values including percentages,…

The bar chart (Invented by William Playfair) is tool used to visually represent categorical data. Categorical data is derived from qualitative data and parsed into discrete groups (Ex. Month of Year, Country of Origin). This form of visualization lends itself best for comparison between categories of data. The bar chart…

Bump charts offer viewers a concept of ranking by comparing values of similar entities over time or place. Line, Area, and Stream graphs are close in composition to bump charts, with the main difference being each line represents an entity within a certain category, and the comparitive value (ranking) is…

Values Represented: Multivariate, numerical data. These visualization tools allow comparison between many variables together to be able to see the relationships between them and bring visibility to outliers. For example, you may want to compare the specs of a specific product from multiple brands. The plots can easily become cluttered…

Sankey diagrams are a specific type of flow diagram, in which the width of the arrows is shown proportionally to the flow quantity. example of a Sankey Diagram on Average US Household SpendingHistory Created in 1898 by Captain Matthew Henry Phineas Riall Sankey, who used this type of diagram to…

They are used to convey a relationship between two variables, such as change over time of a particular characteristic.They are useful for demonstrating things like income increase over time, temperature increase with energy increase, ect..Data could be integers, fractions, percentages, ect.. however, the x axis must be ordered.…

This is a collective research project providing examples and discussion of the basic building blocks of visual data representation.…
