Pie Chart Examples and Templates

"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.

Use this pie chart template in the ConceptDraw PRO diagramming and vector drawing software to add pie charts to your business documents, websites, presentation slides and infographics.
"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.
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. 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. 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."

This wheel diagram sample was created on the base of figure illustrating the webpage "Chapter 3: Current State of the Ecosystem" of the website of the National Broadband Plan of US Federal Communications Comission (FCC). "The broadband ecosystem includes applications and content: e-mail, search, news, maps, sales and marketing applications used by businesses, user-generated video and hundreds of thousands of more specialized uses. Ultimately, the value of broadband is realized when it delivers useful applications and content to end-users.
Applications run on devices that attach to the network and allow users to communicate: computers, smartphones, set-top boxes, e-book readers, sensors, private branch exchanges (PBX), local area network routers, modems and an ever-growing list of other devices. New devices mean new opportunities for applications and content.
Finally, broadband networks can take multiple forms: wired or wireless, fixed or mobile, terrestrial or satellite. Different types of networks have different capabilities, benefits and costs.
The value of being connected to the network increases as more people and businesses choose to adopt broadband and use applications and devices that the network supports. Several factors contribute to their decisions. These include whether they can afford a connection, whether they are comfortable with digital technology and whether they believe broadband is useful.
Networks, devices and applications drive each other in a virtuous cycle. If networks are fast, reliable and widely available, companies produce more powerful, more capable devices to connect to those networks. These devices, in turn, encourage innovators and entrepreneurs to develop exciting applications and content. These new applications draw interest among end-users, bring new users online and increase use among those who already subscribe to broadband services. This growth in the broadband ecosystem reinforces the cycle, encouraging service providers to boost the speed, functionality and reach of their networks."
