Question

This jsfiddle contains a google org chart that represents a family tree for Mike, whose parents Jim & Alice are also brother and sister. [this is a simplification of a real world problem].

The org chart is not displaying the parents of Alice. How can I force the full tree to be represented?

        data.addRows([
      ['Mike', ''],
      ['Jim', 'Mike'],
      ['Alice', 'Mike'],

      ['Bob', 'Alice'],
      ['Carol', 'Alice'],

      ['Bob', 'Jim'],
      ['Carol', 'Jim']

    ]);

Answer 1

Your column names need to be unique. I updated your fiddle:

['Mike', ''],
['Jim', 'Mike'],
['Alice', 'Mike'],

['Bob', 'Jim'],
['Carol', 'Jim'],

['Bob2', 'Alice'],
['Carol2', 'Alice']

From the data property description of google org charts:

Column 0 - The node ID. It should be unique among all nodes
