Network chart

The network chart in Hubstream Classic helps users visualise links associated with an investigation. It shows the flow of information and the relationships between different links of an investigation.

Once one or more links have been added to an investigation, follow the steps given below to view the network chart:

From the user dashboard, click on an investigation to open it.
Once in, open the side bar and click on Links. A list view of links will open.
On the top right, there will be a grid icon called View. Click on it.
From the dropdown that opens, select Network Visualization. The view will change to a network chart of links.
Some links in the network chart will have a circle on the top right containing a plus sign followed by the number of related links.

Click on the circle to expand the network chart and view the related links. The number disappears when the node is expanded. Click on the empty circle to close the expanded node.
On the left side of the network chart, various filters are present. The network chart can be filtered using different entity types, link names or link quality. The type of filters shown depend on the type of links available and their field values.

Click on any filter to apply it. The network chart will change accordingly.
On the top right of the network chart, various options to modify it are available
1. Add: The first one is the plus icon that lets the user add more links to the current investigation.
```
  Click on the plus icon to open the dropdown. Choose the desired type of link, add details and click on Save and close. The new link will be added to the current investigation. Expand the current investigation node to view it.
