A 3D pie chart, or perspective pie chart, is used to give the chart a 3D look. Often used for aesthetic reasons, the third dimension does not improve the reading of the data; on the contrary, these plots are difficult to interpret because of the distorted effect of perspective associated with the third dimension.

Example of a pie chart, along with a bar plot showing the same data and indicating that the pie chart is not the best possible chart for this particular dataset. The graphic was created by User:Schutz for Wikipedia on 28 August 2007 using the R statistical project. The program that generated the graphic is given below.
A pie chart shows percentage values as a slice of a pie; first introduced by William Playfair. [5] A line chart is a two-dimensional scatterplot of ordered observations where the observations are connected following their order. The first known line charts are usually credited to Francis Hauksbee, Nicolaus Samuel Cruquius, Johann Heinrich ...
William Playfair is usually credited with inventing the area charts as well as the line, bar, and pie charts.His book The Commercial and Political Atlas, published in 1786, contained a number of time-series graphs, including Interest of the National Debt from the Revolution and Chart of all the Imports and Exports to and from England from the Year 1700 to 1782 that are often described as the ...
For example, dot plots and bar charts outperform pie charts. [ 30 ] In his 1983 book The Visual Display of Quantitative Information , [ 31 ] Edward Tufte defines 'graphical displays' and principles for effective graphical display in the following passage: "Excellence in statistical graphics consists of complex ideas communicated with clarity ...
The usage of percentages as labels on a pie chart can be misleading when the sample size is small. [8] Making a pie chart 3D or adding a slant will make interpretation difficult due to distorted effect of perspective. [9] Bar-charted pie graphs in which the height of the slices is varied may confuse the reader. [9]
A sina plot is a type of diagram in which numerical data are depicted by points distributed in such a way that the width of the point distribution is proportional to the kernel density. [ 1 ] [ 2 ] Sina plots are similar to violin plots , but while violin plots depict kernel density, sina plots depict the points themselves.
