Here are some tips that help you with the transformation:

Each entity table is represented by a label on nodes
Each row in a entity table is a node
Columns on those tables become node properties.
Remove technical primary keys, keep business primary keys
Add unique constraints for business primary keys, add indexes for frequent lookup attributes
Replace foreign keys with relationships to the other table, remove them afterwards
Remove data with default values, no need to store those
Data in tables that is denormalized and duplicated might have to be pulled out into separate nodes to get a cleaner model.
Indexed column names, might indicate an array property (like email1, email2, email3)
Join tables are transformed into relationships, columns on those tables become relationship properties
