reactive web visualisation of data in neo4j

i need to extend, or create project similar to [login to view URL] , where result of query will be updated in realtime in case database is changed.... user case: user will execute query. If he will keep result opened, result will be updated automatically if data in neo4j are changed on background(i.e by somebody else) i.e if result is 2 nodes conected by edge & node1 is deleted in db by somebody else, i expect this will be updated automatically. I need this to be done reactivly - not by some periodic resending query to db... - code must not be depending on internet - as part of project all source code will be provided.
