6. The computing system of claim 1 , wherein the first depth graph comprises a first attribute graph plotting attribute values measured at different depths associated with the location of the first physical structure. 7. The computing system of claim 6 , wherein the computer readable storage medium further stores program instructions that cause the computing system to: receive a selection of a second attribute graph plotting attribute values measured at different depths associated with the location of the second physical structure; and update the user interface data such that the first depth graph displays the second attribute graph adjacent to the first attribute graph.
