# Advanced pie chart

The Advanced Pie Chart displays data in a circle divided into segments or slices, which are proportional to the represented values. It is possible to create more complex charts than with [Basic Pie Charts](https://docs.appfarm.io/library/ui-components/basic-pie-chart). For example, the Category Property is not limited to some data types and more visual properties are available.  

## Usage

Advanced Pie Charts are used to show data as a percentage of a whole.
