Org Chart

I  have a requirement for an organizational chart. 
I have an employee-specific table in the database containing the reporting manager column and role.
I tried the code but it doesn't expand to down-level resources. I require a dynamic chart to add employees and roles.

a!localVariables(
local!user: loggedInUser(),
a!orgChartField(
value: local!user,
saveInto: local!user,
showAllAncestors: true,
showTotalCounts:true
)
)
