Pie chart

From WikiMD's medical encyclopedia

Pie Chart

A Pie chart is a type of graph that displays data in a circular format, with 'slices' representing each category's proportionate share of the whole. The size of each slice is proportional to the quantity it represents from the total data set.

Pie charts are widely used in business, media, and education to present data in a clear, visual way. They are particularly useful for displaying data that is classified into nominal or ordinal categories.

History

The pie chart was first developed by William Playfair, a Scottish engineer and political economist, in the late 18th century. Playfair is also credited with inventing the line graph and the bar graph.

Usage

Pie charts are used to compare the size of individual categories to the whole. They are most effective when used to represent data with small numbers of categories, and where the proportion of each category is relatively different.

Criticism

Despite their widespread use, pie charts have been criticized by some experts in the field of data visualization. Critics argue that pie charts often fail to provide accurate representations of data, particularly when the data set includes similar proportions.
