Output Shape / area

An Area Chart or area graph are basically a line graph with the area below the lined filled with colors or textures. Like line graphs area charts are  used to represent the development of quantitative values over a time period. It can also be used to compare two or more categories and is similar to the Stacked Area Chart.
Area charts often used to show overall trends over time rather than specific values.

Area Chart

A compound data vizulisation type, combining a scaled timeline with an area chart, a line graph or similar to show the development. It is useful to explain big changes in the development with events or causes. The events are typically visualized with labels anchored to the timeline.

Development & Causes

A violin plot is a method of plotting numeric data. It is a box plot with a rotated kernel density plot on each side. The violin plot is similar to box plots, except that they also show the probability density of the data at different values. Typically violin plots will include a marker for the median of the data and a box indicating the interquartile range, as in standard box plots.

Violin Plot

Stacked Area Chart is similar to the simple Area Chart, but here is uses multiple data series that start each point from the point left by the previous series. It is useful for comparing multiple variables changing over interval.

Stacked Area Chart

A Layered Proportional Area Chart 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 circle shaped forms.

Nested Proportional Area Chart

Stacked ordered area chart is geared towards showing rank change. Use it instead of a stacked area chart when you want to show the change of order over time. The inner categories are connected by ribbons across the columns to help you visually see how the rank changes across the columns.
A similar visualization type is the sorted stream graph

Stacked Ordered Area Chart

A Sorted Stream Graph is area graph which is displaced around a central axis, resulting in a flowing, organic shape – but it is sorted instead of stacked.

The hive plot is a rational visualization method for drawing networks. Nodes are mapped to and positioned on radially distributed linear axes — this mapping is based on network structural properties. Edges are drawn as curved links. Simple and interpretable.
The purpose of the hive plot is to establish a new baseline for visualization of large networks — a method that is both general and tunable and useful as a starting point in visually exploring network structure.

Parallel Sets are a new method for the visualization and interactive exploration of categorical data that shows data frequencies instead of the individual data points. The method is based on the axis layout of parallel coordinates, with boxes representing the categories and parallelograms between the axes showing the relations between categories.

Parallel Sets

A curved bar chart is a variation of bar chart where curved areas are used instead of rectangles. Height of each curved area is proportional to the values it represents. The curved areas can be plotted vertically or horizontally. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value.
Curved bar charts are often seen in modern infographics, but are criticized for being confusing and inaccurate compared to a normal bar chart, as the curved area actually only has one dimension, which is the height.

Sankey diagrams are a specific type of flow diagram, in which the width of the arrows is shown proportionally to the flow quantity. They are typically used to visualize energy or material or cost transfers between processes. They can also visualize the energy accounts or material flow accounts on a community level. Sankey diagrams put a visual emphasis on the major transfers or flows within a system. They are helpful in locating dominant contributions to an overall flow.

A streamgraph, or stream graph, is a type of stacked area graph which is displaced around a central axis, resulting in a flowing, organic shape. Streamgraphs were developed by Lee Byron.

A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions at which thermodynamically distinct phases can occur at equilibrium. Common components of a phase diagram are lines of equilibrium or phase boundaries, which refer to lines that mark conditions under which multiple phases can coexist at equilibrium. Phase transitions occur along lines of equilibrium.

Phase Diagram

Layered area chart is basically multiple area charts layered by either making use of transparency or perspective. It can be used instead of a line graph with multiple graphs to compare development or trend over time.
The visualization may cause some issues in readability when overlapping.

Layered Area Chart

Alluvial diagrams are a type of flow diagram originally developed to represent changes in network structure over time. In allusion to both their visual appearance and their emphasis on flow, alluvial diagrams are named after alluvial fans that are naturally formed by the soil deposited from streaming water.
Variables are assigned to vertical axes that are parallel. Values are represented with blocks on each axis. The height of a block represents the size of the cluster and the height of a stream field represents the size of the components contained in both blocks connected by the stream field.
Alluvial diagram is a variant of the Parallel Sets but for categorical variables and often to display trends over time and phases.

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 Contour Plot is a graphic representation of the relationships among three numeric variables in two dimensions. Two variables are for X and Y axes, and a third variable Z is for contour levels. The contour levels are plotted as curves; the area between curves can be color coded to indicate interpolated values.
The contour plot is an alternative to a 3-D surface plot.

Contour Plot

In addition to the Ternary Plot, you will also find the Ternary Contour Plot. These plots can be used for example to chart the response of an independent variable to changes in a mixture of three components.

Ternary Contour Plot

A range area chart is a variation of an area chart that lets you plot bands of data, such as Bollinger bands and weather patterns. Each point in the chart is specified by two y values.

Range Area Chart

A Waterfall Plot is a three-dimensional plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with ‘nearer’ curves masking the ones behind. The result is a series of “mountain” shapes that appear to be side by side. The waterfall plot is often used to show how two-dimensional information changes over time or some other variable such as rpm.
Not to be confused with the similarly named Waterfall Chart.

Waterfall Plot

A three-dimensional Stream Graph is the graph of a function f(x, y) of two variables, or the graph of a relationship g(x, y, z) among three variables.Provided that x, y, and z or f(x, y) are real numbers, the graph can be represented as a planar or curved surface in a three-dimensional Cartesian coordinate system. A three-dimensional graph is typically drawn on a two-dimensional page or screen using perspective methods, so that one of the dimensions appears to be coming out of the page.
