This example illustrates how to add nodes without paths.
You basically do four things:
In your data file (JSON or csv), data is specified as a collection of paths. For the nodes you want free flowing (no path) you create an "artificial" path to a dummy node, with the name " ". So the label on the axis is invisible.
with sequenceExplorer.eventOrder([...]) you specify the order of the events along the Y axis. Put your dummy event " " to the top (last element in array)
add css to make nodes for the dummy event " " invisible as well as all paths leading to these nodes. (a " " (space) in the event name is substituted to "_" underscore so you can address it with CSS classes.
to have a nice scaling of your nodes/paths, you can add a dummy path from the event " " to the event " " which will be invisible. But if the value of the node is the largest overall, the remaining nodes/ paths are scaled accordingly.
