Have an excel with a list of persons. I have their levels in the hierarchy
with the following structure :

Top Node-Node0
Node1-node11, node12, node13, node14...
node11-node111, node112, node113, node114,...
node111-node1111, node1112, node1113, node1114...

Node2-node21, node22, node23, node24...
node21-node211, node212, node213, node214,...
node211-node2111, node2112, node2113, node2114...


With the above hierarchy, is there a wizard that automates the process of
creating ORG CHARTS in sunflower model...

i.e., Node0 in the centre, Node1, node2, node3... with node11 node12 node13
around node1, node111 node112 node113 around node11, etc.

Microsoft's Visio has a feature like that; see:

I'm not running the latest version, so I can't give you the specifics,
but you might check it out if you haven't found a solution yet.
