Hi @prudhvi.vuda ,
As far as I know, the hover will appear on the top of points, which is your nodes.
By default you cannot put hover text on the top of line (edges).
If you want hover over the edges, you can use interpolate modul from scipy to generate points between two nodes and set hovertext about those new generated points as edge’s data.
