Network Viewer

This node creates a cytoscape.js library based visualisation of the input network and allows to easily display and manipulate created interactive graph.

The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. You will find the list of available classes and their description on our documentation page.
