Representation of the data of a qualitative statistical characteristic based on a grid in the form of a pencil of half-lines with the same origin divided into units of measurement and where the frequency of the data is represented by points connected to one another by segments to form a polygon.

In a web diagram, there are as many axes as modalities. Each axis, which emerges from the same point, represents a quantified characteristic. This type of diagram is only useful if the axes are correctly standardized based on the importance given to each characteristic.

One example of how to use it is to represent the distribution of wind speeds in a given geographical area over a given period.

A web diagram is sometimes called a **radar chart**.

### Example

**Distribution of production**

(based on the number of units of each product)
