Network graph – an overview
What is it for?
Use this template to visualize connections.
Nodes represent data points and links represent the connections between them to represent their connections and help illuminate the type of relationships between a group of entities.
You can choose between an "undirected" and a "directed" network graph. While undirected Network Diagrams only display the connections between entities, directed Network Diagrams show if the connections are one-way or two-way through small arrows.
How to get started
There are two different sheets in the default network graph. You can switch between them by clicking on one or the other in the top left in your data view.
- 1
- The first sheet is the "Links" sheet. This is the minimum data requirement: a two-column list of links. Each row in the list specifies the points (displayed as circles) at either end of a link (displayed as a line). You can optionally include a third column that is used to set the width of the link. (This can be thought of as a visual indicator of the strength or weight of a link.)

- While the "Links" sheet is sufficient to create a network diagram, a second “Points” sheet allows for further flexibility. Rather than letting Flourish determine all the points to add to the network based on those listed in the Links sheet, the rows in the Points sheet define the complete collection of points. This sheet can also be used to assign groups (encoded using colour) and sizes to the points. Here's an example of assigning groups in the "Points" sheet:
-
id group Tyrion 1 Loras 1 Robert Arryn 1 Robert 1 Balon 1 - 3
- Initially, it is assumed that the network diagram is undirected. To set your network to be directional, you can select 'Show arrows on links' in the "Links" settings under the advanced settings.
