Graph Function / Part to whole

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.

Pictorial fraction chart is a very simple way of displaying data, but it is also widely used. Good use of it includes creativity, illustrations, typography, etc.

A progress bar is a graphical control element used to visualize the progression of an extended operation, such as a download, file transfer, or installation. Sometimes, the graphic is accompanied by a textual representation of the progress in a percent or quantitative format.

Progress Bar

A chart type that is using pictograms (icons, pictures, illustrations, etc.) to show fractions – e.g. one in five people eat five or more portions of fruit and vegetables a day. It is a very illustrative data visualization and has become quite popular in modern infographics for simple facts.
A related visualization is the Pictorial Fraction Chart that visualize percentages.

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 Pictorial Stacked Chart is similar to the Stacked Bar Chart, but the bar is replaced by a pictogram in order to represent the percentage stacked in pictogram.

Stacked Bar Chart is neither Multi-set Bar Chart nor simple Bar Chart. Stacked Bar Chart is multiple datasets on top of each other in order to show how the larger category is divided into the smaller categories and their relations to the total amount. 
Basically, they can be divided into two types:
1) Simple Stacked Bar Chart displays total value of the bar is all the segment values added together.
2) 100% Stack Bar Chart displays part to whole relationship in each group.

Stacked Bar Chart

A funnel chart is used to show streamlined data; each slice in the funnel represents a process that has filtered out data. The last funnel bears the value that is the final result of the entire procedure.
A funnel chart displays values as progressively decreasing proportions amounting to 100 percent in total. The size of the area is determined by the series value as a percentage of the total of all values. Any funnel consists of the higher part called head (or base) and the lower part referred to as neck.
Ideally, the funnel chart shows a process that starts at 100% and ends with a lower percentage where it is noticeable in what stages the fall out happens and at what rate. If the chart is also combined with research data, meaning quantified measurements of just how many items are lost at each step of the sales or order fulfillment process, then the funnel chart illustrates where the biggest bottlenecks are in the process.

A waffle chart shows progress towards a target or a completion percentage. There is a grid of small cells, of which coloured cells represent the data.
A chart can consist of one category or several categories. Multiple waffle charts can be put together to show a comparison between different charts.

A pyramid chart is an inverted funnel chart. Similar to a funnel chart, the pyramid chart is a single series chart which does not use an axis. It represents data as portions of a 100% (the individual segments add up to represent a whole).

Pyramid Chart

The multi-level pie chart is a special type of chart that allows you to show symmetrical/asymmetrical tree structures in a consolidated pie-like structure.
Though similar, the multilevel piechart should not be confused with the multi-level donut chart, as it contains no connected hierarchy and tree structure, but only displays independant donut rings for comparison.

Multi-level Pie 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 Bullet Graph is a variation of a Bar Graph. Seemingly inspired by the traditional thermometer charts and progress bars found in many dashboards, the bullet graph serves as a replacement for dashboard gauges and meters. Bullet graphs were developed to overcome the fundamental issues of gauges and meters: they typically display too little information, require too much space, and are cluttered with useless and distracting decoration.

A Mekko chart (also called marimekko chart) is a two-dimensional stacked chart. In addition to the varying segment heights of a regular stacked chart, a Mekko chart also has varying column widths. Column widths are scaled such that the total width matches the desired chart width.
