🔭 見 see + 渡す span across: seeing that sweeps from one side of a scene to the other
渡 comes from 渡る (wataru), to cross a river or bridge. 渡す adds a sense of spanning across, so 見渡す means your seeing crosses the whole scene from edge to edge.
渡 — water radical 氵 + 度 (measure/cross)
渡 combines the water radical 氵 with 度, which provides the sound and suggests measuring or passing across. Originally it meant to cross a body of water, like fording a river or ferrying across. Over time it broadened to mean 'to pass through' any transition, including time or stages of life.
