A donut chart (also spelled doughnut) is functionally identical to a pie chart, with the exception of a blank center and the ability to support multiple statistics at once. Doughnut charts provide a better data intensity ratio to standard pie charts since the blank center can be used to display additional, related data.

Donut Chart

A pie chart is divided into sectors, illustrating numerical proportion. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented.

Pie Chart

Angular Gauge uses a radial scale to display a specific data point using a dial over a radial scale with defined limits. Colors can be associated for the sections of the data to indicate categories for values.
Angular gauges can be used for many purposes like speed, satisfaction, volume, temperature, etc. But most common use is from car dashboard for fuel, speed, etc. also known as speedometer.

Angular Gauge

The Angular Index Gauge is quite similar to the Angular Gauge, but it doesn’t necessary display specific data/number. But this is very useful for indication of index of whether something is good/bad, high/low, above average, etc.

Solid Gauge Chart

A Bubble Map Chart is simply a combination of a bubble chart data visualization and a map. It is used to visualize location and proportaion in a simple way.

Bubble Map Chart

A Proportional Area Chart (Circle) is used for comparing proportions (size, quantities, etc.) to provide a quick overview of the relative size of data without the use of scales. You can also find a variant of this with square shaped forms.

Proportional Area Chart (Circle)

Semi Circle Donut Chart is simply a Donut Chart cut in half. The elements are still divided into sectors, illustrating numerical proportion like a basic pie or donut chart.

A Venn diagram or set diagram is a diagram that shows all possible logical relations between a finite collection of sets. Venn diagrams were conceived around 1880 by John Venn. They are used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.

Venn Diagram

A Sunburst Diagram is used to visualize hierarchical data, depicted by concentric circles. The circle in the centre represents the root node, with the hierarchy moving outward from the center. A segment of the inner circle bears a hierarchical relationship to those segments of the outer circle which lie within the angular sweep of the parent segment.
A sunburst chart without any hierarchical data (one level of categories), looks similar to a doughnut chart. However, a sunburst chart with multiple levels of categories shows how the outer rings relate to the inner rings.

Sunburst Diagram

Multi-level Donut charts are a set of concentric circles which is used to visualize hierarchical relationships. The size of each item represents its contribution to the inner parent category. It starts with a single item that is put as a circle in the center. This is the root node. A concentric ring is set around this central circle to see the breakup of that item. The concentric ring is then segmented to show how various child items have contributed to the parent item.

Multi-level Donut Chart

A bubble chart is a type of chart that displays three dimensions of data. Each entity with its triplet (v1, v2, v3) of associated data is plotted as a disk that expresses two of the vi values through the disk’s xy location and the third through its size. Bubble charts can facilitate the understanding of social, economical, medical, and other scientific relationships. Bubble charts can be considered a variation of the scatter plot, in which the data points are replaced with bubbles.

Bubble Chart

A Cycle Diagram is simply used to show how a series of events interact repeatedly through a cycle. It normally refers to a repetitive flow of actions/steps which doesn’t really have a start and/or a proper end.

Cycle Diagram

A Bubble timeline is a way to display a set of events or items on a timeline with a variable displayed as the the are size of the bubbles. In essence the bubble timeline is a compound data visualization, of a scaled timeline and a proportional area chart.

Bubble Timeline

A Radial/Circular Bar Chart simply refers to a typical Bar Chart displayed on a polar coordinate system, instead of a cartesian system.It is used to show comparisons among categories by using a circular shape.

Radial Bar Chart

A Radial or Circular Histogram is used for displaying the circular data, which involves the wrapping of the usual histogram around a circle. Each bar in the histogram is centered at the middle of the group period with the length of the bar proportional to the frequency in the group.

Radial Histogram

Circle Packing is a method to visualize large amounts of hierarchically structured data. Tangent circles represent brother nodes at the same level; to visualize the hierarchy, all children of a node are packed into that node (and thus determine its size). The size of a leaf-node can represent an arbitrary property, such as file size. An advantage of this algorithm is the good overview of large data sets and the clear representation of groupings and structural relationships.

Packed Circle Chart

Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters). It is a main task of exploratory data mining, and a common technique for statistical data analysis, used in many fields, including machine learning, pattern recognition, image analysis, information retrieval, and bioinformatics.

Cluster Analysis

An Euler Diagram is a diagrammatic means of representing sets and their relationships. They are closely related to Venn diagrams. Euler Diagrams consist of simple closed curves (usually circles) in the plane that depict sets. The sizes or shapes of the curves are not important: the significance of the diagram is in how they overlap. The spatial relationships between the regions bounded by each curve (overlap, containment or neither) corresponds to set-theoretic relationships (intersection, subset and disjointness).

Euler Diagram

A Target Diagram displays progress towards a goal. Each layer moves closer towards the centre result. It reminds a bit like a flow chart which moves from the outside to the centre. Each layer can also be divided into subcategories.

Target Diagram

Bubble pie chart is a unique bubble chart that allows you to show/compare/relate performance across four paramenter sets instead of two. The third value determines the size of the bubble marker, the fourth by the % of pie while the other two are determined by the position on the axis.

Compound Bubble and Pie Chart

A process diagram simply displays a process with start and end point. It can be visualized in many shapes, designs with various of process steps.

Process Diagram

A Proportional Area Chart (Half Circle) is a variation of Proportional Area Chart (Circle), where one measure is represented as a circle. Representing two data sets in one circle (half circle each), this visualisation is useful for comparing two data sets (I,II in the input type) within one category and as well between different categories (A,B,C in the input type). Two data sets are often two different years or two contrary concepts (A/A’, male/female, etc.) It is also possible to use it for only one category (one circle).

Proportional Area Chart (Half Circle)

A fan chart,  is a chart representing family relationships in a tree structure. It features a half circle chart with concentric rings: the person of interest is the inner circle, the second circle is divided in two (each side is one parent), the third circle is divided in four, and so forth. Fan charts depict paternal and maternal ancestors.

Fan Chart (Geneaology)

The Polar Area chart is similar to a usual pie chart, except sectors are equal angles and differ rather in how far each sector extends from the center of the circle. The polar area diagram is used to plot cyclic phenomena (e.g., count of deaths by month).

Polar Area Chart

A spiral heat map is a specific type of heat map designed for continuous comparable cycles like years or days. The spiral design makes it possible to compare the cycles, but keeping the continuous timeline along the spiral.

Spiral Heat Map

Nested circles allow to represent hierarchies and compare values. This visualization is particularly effective to show the proportion between elements through their areas and their position inside a hierarchical structure.

Clustered Force Layout

A radial heat map is a variation of heat map, where the table is aligned radially. A heat map is a graphical representation of data where the individual values contained in a matrix are represented as colors. Fractal maps and tree maps both often use a similar system of color-coding to represent the values taken by a variable in a hierarchy. The term is also used to mean its thematic application as a choropleth map. The term “Heatmap” was originally coined and trademarked by software designer Cormac Kinney in 1991, to describe a 2D display depicting real time financial market information.

Circular Heat Map

Radial Area Chart is a variation of Area Chart. An area chart displays graphically quantitive data. It is based on the line chart. The area between axis and line are commonly emphasized with colors, textures and hatchings. Whereas area charts are used to represent cumulated totals using numbers or percentages over time, Radial Area Chart can be also used to display categories instead.

Radial Area Chart

A Non-ribbon Chord Diagram is a stripped-down version of a Chord Diagram, with only the connection lines showing. This provides more emphasis on the connections within the data. A chord diagram is a graphical method of displaying the inter-relationships between data in a matrix. The data is arranged radially around a circle with the relationships between the points.

Radial Line Graph is a part of radial graphs that takes data and render it as collection of data points wrapped around a circle. It is also mapping a list of categories from the minimum to the maximum of the extent of the chart. Radial Line Graph is rendered using a collection of straight lines connecting data points.

Radial Line Graph

Radial Convergences are used to visualize relationships between entities. Entities are displayed as round nodes and lines show the relationships between them. It is similar to a network visualization but it is arranged in strict circular layout.
