Data Visualization & Information Aesthetics

This viz-type belongs to the same family as Sankey Diagrams and Radar Charts. The best use cases apply to multi-variate datasets, which require plotting individual data elements across many dimensions. Basic Properties:Each of the dimensions corresponds to a vertical axis and each data element is displayed as a series…

A matrix is any two dimensional set of numbers, colors, intensities, sized dots or other glyphs. With ‘simple’ matrices, variations along a third or even fourth variable are often represented by color ranges and other types of visual variations between cells on the matrix. Half matrices are usually used for…

DefinitionA Voronoi diagram consists of a plane partitioned by a set of n points into convex polygons, such that each polygon contains one generating point and represents the region of points around it that is closer to this generating point than any other.Basic PropertiesGenerators/sites/seeds: finite set of…

Not much detailed description is needed when speaking about a table. One of, if not the, purest forms of visualization, a table simply displays data in an organized manner, more specifically, in rows and columns. With this simplicity comes flexibility in what data is represented. Whether it’s text, numbers,…

What is a Dendrogram?A Dendrogram demonstrates the hierarchical relationship between objects.We can think of Dendrograms as a way to represents nested clusters.2. How to read a Dendrogram?The key is to focus on the height at which any two objects are joined together. Look at the image…

OverviewHistograms are a powerful visualization tool, but are often confused with bar charts and as we will see below many of the bad examples of histograms come from people trying to hack a histogram out of a bar chart.  Histograms are generally used for continuous data sets, where the goal…

a two dimensional plot featuring a box capped by the 1st and 3rd quartiles, spliced by the median line, and with "whiskers" extending to min and max values alternatively, if outliers are present (1.5 x IQR), the whiskers may span the least and greatest non outlier range, with outliers…

Physical maps order elements by physical location, such as latitude and longitude points.Cartogram types of maps distort reality to convey information. They resize and exaggerate any variable on an attribute value.Density-equalizing cartograms are your traditional cartograms. In density-equalizing cartograms, map features bulge out a specific variable. Even though…

bar graph is a graphical way to display data using bars vertically or horizontally in x and y axis.usually one axis shows the categories and the other axis shows percentages. bar graphs are used for comparison and representing relationship between groups with different data.bar graph components:x and…

What is it? A scatter plot is a two dimensional chart that uses points or “dots” to represent specific values.Scatter plots most commonly have two different values that are represented using the X and Y axis. This specific type of chart is best used to show the relationship between…

Visual Diff is a differencing representation that shows the difference between two objects(Text documents, pictures, etc). For instance, two columns of text connected by lines to show where changes have been made.  or two documents with the color bar on the text which highlights the adding and deleting have…

created in 1973 by Herman Chernoff - an applied mathematicianThe Chernoff 'faces'  (called GLYPHs - a symbol or pictograph) are probably the easiest and possibly the most humanistic way of visualizing data.  Its called a 'MULTIVARIATE' (or more than 2 variables ) ANALYSIS.  These faces are universal, quick and easy.   All…

What's Its Purpose?A survey plot, also known as a side by side bar chart or Table Lens' main purpose is to visualize patterns and outliers in multivariate datasets. In its simplified form, a Table Lens graph is a way to cluster relationships using bars. They are normally sorted independently…

A Tree is largely used to show ordered data by connecting lines between those points akin to the branches of a tree. In slight contrast to tree maps, Tree Graphs are a collection of nodes that eliminate the need to display hierarchy when it isn't relevant factor to the data's…

Idiom Line Charts What: Data One quantitative value, one ordered attribute How: Encode Points with connection marks between them Why Show trend Scale Hundreds of levels of the ordered attribute Line charts displays one value attribute and one key attribute in a  2-D space, while showing categorical attribute using colors…

A heat map is a representation of data in maps or diagrams in which values (mostly continuous data) are encoded as color in form of a gradient, which can range from two color hues to the use of the full rainbow spectrum.It is not necessary to have every single…
