PYSPARK：如何可視化GraphFrame？

Question

假設我創建了以下圖表。我的問題是如何可視化它？

# 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) 

Answer 1

我找不到任何可視化數據的原生GraphFrame庫。儘管如此，您可以嘗試使用display（）函數從DataBricks中執行此操作。你可以看到一個例子here。

此外，您可以嘗試將GraphFrame轉換爲python列表，並使用matplotlib或Pygraphviz庫。
