You can change the sibling distance
for each level of the tree individually, using level <number>/.style={sibling distance=<value>}
:
\documentclass[a4paper,landscape]{scrartcl}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[
auto,
level 1/.style={sibling distance=40mm},
level 2/.style={sibling distance=10mm}]
\node [circle,draw] (z){0}
child {
node[circle,draw] (a) {1}
child {
node[circle,draw] (c) {5}
}
child {
node[circle,draw] (d) {5}
}
child {
node[circle,draw] (e) {5}
}
child {
node[circle,draw] (f) {5}
}
}
child {
node[circle,draw] (b) {2}
}
;
\end{tikzpicture}
\end{document}
Some marginal improvements can be achieved by setting the width of all the boxes, as I have done below. However, this particular choice of tree-structure (even for an organization chart is difficult to accomodate on an A3 or A4 paper). Imagine the grandchildren spaced horizontally and we are in trouble if we need to grow the tree one further level.
A better approach is to draw such charts as a directory tree. These type of grids are more economical in terms of horizontal spacing. Here is an example drawn using dirtree
.
Since the figure mostly consist of text, the using of boxing is extraneous in the example above, however the dirtree
can easily be extended to hold tikz nodes rather than text.
Another advantage of the above is that in the particular example I have shown in the illustration information was captured in a more intuitive and semantic way,
.6 \addCADMech{\hl{Dhanish Chandran}}.
.6 \addCADMech{\hl{Sogy George}}.
.6 \addCADMech{\hl{Jhonas Marquez}}.
.6 \addCADMech{\hl{Prasad Balakrishnan}}.
This also permitted automatic recalculation of totals and the production of a summary table. This is perhaps not a full answer, but you are asking to produce a layout which will break in most circumstances. The proper solution is to produce a dirtree
type solution either with dirtree
or with TikZ following such a pattern.
The MWE would produce the image above.

Best Answer
Tikz builds the tree in such a way that the length
level distance
is the distance between the pointgrowth parent anchor
and the anchor of the child.By default, the
growth parent anchor
iscenter
. And the anchor of the children are the default nodes anchors, which are alsocenter
. So you get 1cm between the centers of the nodes.In order to have 1cm between the edges of the nodes as you request, you have to set
growth parent anchor
tosouth
, and set also the defaultanchor
for all the nodes of the tree tonorth
. The following code implements this idea (and adds some blue lines to test if it works).It works! See the result:
