1. A method comprising: obtaining, by a computer system, data regarding a trajectory of a wellbore; obtaining, by the computer system, a first data set related to a first physical parameter of a formation penetrated by the wellbore, the first data set including values of the first physical parameter of the formation along the trajectory of the wellbore; displaying on a display device of the computer system a two-dimensional representation of a three-dimensional trajectory of the wellbore from a viewpoint relative to the three-dimensional trajectory of the wellbore; displaying a mathematical curve representing the first data set on a first surface that extends along and abuts the displayed two-dimensional representation of the three-dimensional trajectory of the wellbore on the display device such that the first surface has consistent orientation relative to the trajectory of the wellbore, and a relative distance of the mathematical curve from the two-dimensional representation of the three-dimensional trajectory of the wellbore represents a relative magnitude of each of the respective values of the first physical parameter of the formation along the trajectory of the wellbore; and setting a transparency of a texture on the display device between the two-dimensional representation of the three-dimensional trajectory of the wellbore and the mathematical curve on the first surface, based on the relative magnitude of the first physical parameter of the formation.
