Origin 2021b, we introduced Network plot (menu **Plot:Categorical:Network**). It shows the interconnections between a set of entities. Each entity is represented as a node while connections between entities are represented by links between nodes. User can manually drag node around.

The network plot in Origin supports three types of input data: Adjacent Matrix, Incidence Matrix and Edge List:

- Adjacent Matrix: a square matrix where individuals in rows and columns are the same.

- Incidence Matrix: None-squared matrix and the entities in rows and columns are not necessarily the same.

- Edge List: Input has two columns and each row represents a connection between an origin (left column) and a destination (right column).

**Example : Trading of Football Players Within European Countries**

From the graph, we can see the format of the nodes (size, color, position, etc) and the edges (color, thckness) can be customized to carry information.

- The network plot is put on top of the map of Europe where the node position reflects each country’s geographical location.
- The size of each node represent the number of exported players . ( Symbol size can be adjusted to represent incoming players or the total number of transferred players)
- The thickness of each link represents the number of transferred players between two countries.

Below are some Network Plot examples delivered with Origin 2021b. you can choose menu **Help: Learning Center**… Go to **Graph Samples** tab, enter keyword **2021b **and find these graph samples with associated data.
