abutting the border when setting engine='neato'

[Freakwill]

Following is my code to draw HMM graph. If I set engine='neato', the nodes will kiss the border of the box of the clusters, else the nodes are not in the write positions. How do I fix the problem?

import graphviz
g = graphviz.Digraph(comment='HMM', filename='HMM.gv', engine='neato')
g.attr(rankdir='LR')

with g.subgraph(name='cluster_1') as c:
    c.attr(style='dashed', pad="10")
    for k, node in enumerate(['X1','X2', 'XX', 'XT']):
        if node == 'XX':
            c.node(node, label='...', shape='plaintext', pos=f'{k}, 1!')
        else:
            c.node(node, pos=f'{k:f}, 1!')
    # c.attr(label='Observable Variables')

with g.subgraph(name='cluster_2') as c:
    c.attr(style='dashed')
    for k, node in enumerate(['Y1','Y2', 'YY', 'YT']):
        if node == 'YY':
            c.node(node, label='...', shape='plaintext', pos=f'{k}, 0!')
        else:
            c.node(node, pos=f'{k:f}, 0!')
    # c.attr(label='Hiden Variables')

g.edges([('Y1', 'Y2'),('Y2', 'YY'), ('YY', 'YT')])

g.edge('Y1', 'X1')
g.edge('Y2', 'X2')
g.edge('YT', 'XT')

g.view()
