Setting min height of node to avoid overlap issue

[abhimodgi]

I am facing issue due to huge number of nodes in sanky chart. The node height is rendered very small and node text get's overlapped.
Is there a way to set min height of node so that we can avoid overlap issue in case of huge number of nodes.
Or is there a way to change graph size height dynamically based on number of nodes.
