Implement family tree visualization in Graphviz
I am trying to build a family tree with multiple generations using Python Graphviz. I've created functions to ease adding people using their relations (add married couple, add children). Though, I am facing an issue with Graphviz layout such that the edges are overlapping with the nodes when adding marriage and children. It seems like the married people nodes are not being drawn closely together as it should as shown below:
As shown, the case for a couple with no children is perfect but when adding children, the layout seems to be confused.
Here is the layout without the second generation, the layout seems to be fine
The code that I am using to generate
import graphviz
def add_marriage_node(tree, id1, name1, id2, name2):
with tree.subgraph() as sub_tree:
sub_tree.attr(rank='same')
sub_tree.node(str(id1), name1)
sub_tree.node(str(id2), name2)
sub_tree.node('N' + str(id1) + '_' + str(id2),
shape='point',
**{'width':str(0.08)})
tree.edge(str(id1), 'N' + str(id1) + '_' + str(id2))
tree.edge('N' + str(id1) + '_' + str(id2), str(id2))
# Children= [{'id': 1, 'name': 'ChildA'}, {'id': 2, 'name': 'ChildB'}]
def add_children_nodes(tree, father_id, mother_id, children):
# Add parent_children point nodes
with tree.subgraph() as sub_tree:
sub_tree.attr(rank='same')
for child in children:
parent_node = 'N' + str(father_id) + '_' + str(mother_id)
parent_child_node = 'N' + str(father_id) + '_' + str(mother_id) + '_' + str(child['id'])
sub_tree.node(parent_child_node,
shape='point',
**{'width':str(0.08)})
if len(children) % 2 == 0:
center_node = 'N' + str(father_id) + '_' + str(mother_id) + 'B'
sub_tree.node(center_node,
shape='point',
**{'width':str(0.08)})
# Connect parent node to the middle parent_children point or a new center point
if len(children) % 2 == 0:
tree.edge(str(parent_node), str(center_node))
else:
middle_child = children[len(children) // 2]
parent_child_node = 'N' + str(father_id) + '_' + str(mother_id) + '_' + str(middle_child['id'])
tree.node(str(middle_child['id']), str(middle_child['name']))
tree.edge(str(parent_node), str(parent_child_node))
# Connect the parent_children nodes horizontally
i = 0
while i < len(children)-1:
parent_child_node1 = 'N' + str(father_id) + '_' + str(mother_id) + '_' + str(children[i]['id'])
parent_child_node2 = 'N' + str(father_id) + '_' + str(mother_id) + '_' + str(children[i+1]['id'])
if len(children) % 2 == 0 and i == len(children)/2 - 1:
tree.edge(parent_child_node1, center_node)
tree.edge(center_node, parent_child_node2)
else:
tree.edge(parent_child_node1, parent_child_node2)
i += 1
# Add children nodes and connect them to their respective parent_children node
for i in range(len(children)):
parent_child_node = 'N' + str(father_id) + '_' + str(mother_id) + '_' + str(children[i]['id'])
tree.node(str(children[i]['id']), str(children[i]['name']))
tree.edge(parent_child_node, str(children[i]['id']))
tree = graphviz.Graph( engine='dot',

The main issue is the layout as stated above. Other issues are also present in the current implementation if you'd wish to further help are as listed below:
- Change the node shape to rounded corner box
- Formatting the node to have birth date, death date below the name with smaller font and an id with even smaller font at the bottom right corner of the node
- Children edge should connect to the center of the node such that the edge between the point shaped node and the child is of straight line
- Reducing the width of the point shape node shows discontinuity in the line rather than showing a continuous elbowed edge as I hoped
Any help would be greatly appreciated If you think using Graphviz is a bad idea for building a family tree, please suggest other libraries
---- UPDATE ----
Still finding trouble with scalability even after adding clusters and groups. When adding cousins, the layout again gets confused as shown in the tree below:

Solution
You had many leading spaces in your label text. The resulting node width caused(?) the odd placement. Here is your graph with spaces removed, but names padded to believable length:
