  This is a preliminary study of the equation of motion of Euclidean classical
gravity on a graph, based on the Lin-Lu-Yau Ricci curvature on graphs. We
observe that the constant edge weights configuration gives the unique solution
on an infinite tree w.r.t. the asymptotically constant boundary condition. We
study the minimum and maximum of the action w.r.t. certain boundary conditions,
on several types of graphs of interest. We also exhibit a new class of
solutions to the equations of motion on the infinite regular tree.
