Sequence explorer

This example illustrates how to add nodes without paths.

forked from EE2dev‘s block: Sequence explorer - visitor flow

Changes to the forked version above:

to have a nice scaling of your nodes/paths, you can use sequenceExplorer.chart().nodePadding() instead of creating a dummy path from the event “ “ to the event “ “.
the sequence elements are and should be strings not numbers.
colored one specific node with CSS
to refer to a meaningful denominator for the percentages, specify sequenceExplorer.chart().correspondingEvents([]) the related events. (in this case exclude the dummy events)
to add people icons flowing through certain paths, simply add the corresponding paths to the data with a name and call sequenceExplorer.chart().particleShape(“person”)
percentages are set to “%sameEvent”. Change the percentage to the metric most useful for your application.
