Playfair presented an illustration, which contained a series of pie charts. 1858, in particular in maps. Playfair thought that pie charts were in need of a third dimension to add additional information. The use of superfluous dimensions not used to display the data of interest is discouraged for charts in general, not only for pie charts.

Doughnut charts are similar to pie charts in that their aim is to illustrate proportions. This type of circular graph can support multiple statistics at once and it provides a better data intensity ratio to standard pie charts. This effect is used to either highlight a sector, or to highlight smaller segments of the chart with small proportions. The polar area diagram is similar to a usual pie chart, except sectors have equal angles and differ rather in how far each sector extends from the center of the circle. The radius of each sector would be proportional to the square root of the death count for the month, so the area of a sector represents the number of deaths in a month. 1829 paper showing seasonal and daily variation in wind direction over the year and births and deaths by hour of the day. Nightingale published her rose diagram in 1858.

Although the name “coxcomb” has come to be associated with this type of diagram, Nightingale originally used the term to refer to the publication in which this diagram first appeared–an attention-getting book of charts and tables–rather than to this specific type of diagram. The circle in the centre represents the root node, with the hierarchy moving outward from the center. A segment of the inner circle bears a hierarchical relationship to those segments of the outer circle which lie within the angular sweep of the parent segment. A variant of the polar area chart is the spie chart designed by Dror Feitelson. This superimposes a normal pie chart with a modified polar area chart to permit the comparison of two sets of related data. The base pie chart represents the first data set in the usual way, with different slice sizes. The second set is represented by the superimposed polar area chart, using the same angles as the base, and adjusting the radii to fit the data.

For example, the base pie chart could show the distribution of age and gender groups in a population, and the overlay their representation among road casualties. Age and gender groups that are especially susceptible to being involved in accidents then stand out as slices that extend beyond the original pie chart. Square charts are a rare form of pie charts that use squares instead of circles to represent percentages. The table lists the number of seats allocated to each party group, along with the derived percentage of the total that they each make up. Because of rounding, these totals do not add up to 100 and 360. The size of each central angle is proportional to the size of the corresponding quantity, here the number of seats.
