title: PYSPARK: how to visualize a GraphFrame?
body: <p>Suppose that I have created the following graph. My question is how can I visualize it?   </p>
  
  <pre><code> # Create a Vertex DataFrame with unique ID column "id"
      v = sqlContext.createDataFrame([
        ("a", "Alice", 34),
        ("b", "Bob", 36),
        ("c", "Charlie", 30),
      ], ["id", "name", "age"])
      # Create an Edge DataFrame with "src" and "dst" columns
      e = sqlContext.createDataFrame([
        ("a", "b", "friend"),
        ("b", "c", "follow"),
        ("c", "b", "follow"),
      ], ["src", "dst", "relationship"])
      # Create a GraphFrame
      from graphframes import *
      g = GraphFrame(v, e)
  </code></pre>
