Now a days i have problem with creating application Similar to
 (MS Organization Chart).

 As this module has many sections like

  - Data Structure to store each node's data
  - Adjusting the location of node in case of parent that have many
childrens
  - Joining the nodes with lines according to the relation between nodes.
  - Selecting a node by a mouse click & the program will add the nodes
    automatically, by Autocalc the places

 I have no problem , in case of adding nodes in order, but the problem
 appears  when i want to add a node in the middle of this chart.

 I thought about many structures, but they are not so powerfull, as i
search
 for a certain logic that lets me  able to manage all the nodes to adjust
 new places for each node to free space for the comming Node

 I ask if i can get an Algorithm ,component or OCX  that let it easy for
 me to create  this chart

Using a TImage you could paint the whole structure onto.
The OnMousedown would have to be used to change the graph,
then repaint it.
