How to traverse from an starting node in DBpedia sparql?

I have an starting page in dbpedia(https://dbpedia.org/page/Hassan_Rouhani) and I want to traverse his graph only using some specific properties(like dbo:party or dbp:office) until ith depth. I also want to record the connections between entities so i can visualize the graph later. I'm not that skilled in sparql so i'd aprreciate if you can help me.

This is the query that I wrote:

PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX dbp: <http://dbpedia.org/property/>

CONSTRUCT {
  ?entity ?property ?target
}
WHERE {
  {
    <https://dbpedia.org/page/Hassan_Rouhani> ?property ?entity .
    FILTER(?property IN (dbo:party, dbp:office))
    OPTIONAL { ?entity ?property ?target . }
  }
  UNION
  {
    ?entity ?property ?target .
    FILTER(?property IN (dbo:party, dbp:office))
    OPTIONAL { ?target ?property ?next . }
  }
}
LIMIT 100
