Pie Charts

The vector stencils library Pie charts contains 28 templates you can use to add pie and donut charts in your business documents, presentation slides and infographics using the ConceptDraw PRO diagramming and vector drawing software.
"A pie chart (or a circle graph) is a circular chart 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 charts are very widely used in the business world and the mass media. However, they have been criticized, and many experts recommend avoiding them, pointing out that research has shown it is difficult to compare different sections of a given pie chart, or to compare data across different pie charts. Pie charts can be replaced in most cases by other plots such as the bar chart. ...
However, if the goal is to compare a given category (a slice of the pie) with the total (the whole pie) in a single chart and the multiple is close to 25 or 50 percent, then a pie chart can often be more effective than a bar graph. ...
A doughnut chart (also spelled donut) is functionally identical to a pie chart, with the exception of a blank center and the ability to support multiple statistics as one." [Pie chart. Wikipedia]
The example "Design elements - Pie charts" is included in the Pie Charts solution of the Graphs and Charts area in ConceptDraw Solution Park.

The vector stencils library "Composition charts" contains 6 templates: 2 pie charts, 2 divided bar charts and 2 double divided bar charts.
The vector stencils library "Composition indicators" contains 6 templates of visual indicators.
Use these design elements to visualize composition comparison of your data in your visual dashboard created using the ConceptDraw PRO diagramming and vector drawing software.

An obvious flaw exhibited by pie charts is that they cannot show more than a few values without separating the visual encoding (the “slices”) from the data they represent (typically percentages). When slices become too small, pie charts have to rely on colors, textures or arrows so the reader can understand them. This makes them unsuitable for use with larger amounts of data. Pie charts also take up a larger amount of space on the page compared to the more flexible alternative of bar charts, which do not need to have separate legends, and can also display other values such as averages or targets at the same time. ...
Most subjects have difficulty ordering the slices in the pie chart by size; when the bar chart is used the comparison is much easier. Similarly, comparisons between data sets are easier using the bar chart.

Statisticians generally regard pie charts as a poor method of displaying information, and they are uncommon in scientific literature. One reason is that it is more difficult for comparisons to be made between the size of items in a chart when area is used instead of length and when different items are shown as different shapes.
Further, in research performed at AT&T Bell Laboratories, it was shown that comparison by angle was less accurate than comparison by length. This can be illustrated with the diagram to the right, showing three pie charts, and, below each of them, the corresponding bar chart representing the same data.

This ring chart example was created on the base of the figure illustrating the article "A framework for understanding and improving interactions" from the Australian government website DesignGov.
"What do these findings mean for understanding the interactions between business and government and how they might be dramatically improved? The framework described below draws on the needs, insights and findings of the project to identify where initiatives are most likely to lead to better experiences. ...
The integrated framework (depicted in Figure ...) starts from the needs and builds on insights to potential solutions at systemic, agency and individual levels. It consists of five facets of the range of interactions, with each facet being supported by the previous one, and supporting the next in turn. ...
Framework for understanding and improving interactions, displaying how each of the facets support each other...
The five facets impacting interaction are:
(1) Context – Understand me and my context. Knowing who the parties are, what they want, what they do and how these things might be changing. Once this context is understood it allows both parties to better communicate with one another.
(2) Finding answers – Help me find out what I need to know. Having the right information in a form that each party can easily use to determine what is relevant to them. Having strong communication will facilitate better engagement.
(3) Engage – Before making decisions, recognise my experience, my skills and my needs. Consulting and engaging well enough to understand the experiences, expertise and capability, drivers, motivations and needs of the relevant parties so as to ensure effective decision-making. Good decision-making will help to avoid potential problems arising.
(4) Problem solving – Work with me to unravel problems. Understanding problems and issues and if (or how) we contribute to them, and having mechanisms by which to transparently resolve the problems. Effective problem solving capabilities lead to better outcomes and a better service experience.
(5) Respect – Treat me with respect and consideration. Having a strong and adaptable service culture, and listening and responding with respect. This in turn assists in better understanding the parties and their context."
