1. A catheter navigation system comprising:
an input-output device system communicatively connected to a display device system;
a memory device system storing a program; and
a data processing device system communicatively connected to the input-output device system and the memory device system, the data processing device system configured at least by the program at least to:
receive a plurality of location signal sets, each location signal set of the plurality of location signal sets indicative of a respective location in a sequence of locations at which at least a portion of a catheter has sequentially moved to in a bodily cavity, the catheter comprising a plurality of transducers arrangeable in a first spatial distribution;
generate and cause the display device system to progressively visually represent in a progressively enlarging manner, and based on and throughout reception of at least the received plurality of location signal sets, at least a portion of an envelope representing an interior volume of the bodily cavity, the progressively enlarging manner increasing a space represented by the envelope; and
cause the display device system to concurrently display at least (a) the at least the portion of the envelope, and (b) a plurality of graphical elements, each graphical element corresponding to a transducer of the plurality of transducers,
wherein the causing the display device system to concurrently display at least (a) and (b) includes a display of a first set of graphical elements of the plurality of graphical elements and a region of the at least the portion of the envelope in a first graphically-overlapping manner, and with a second set of graphical elements of the plurality of graphical elements displayed in a second graphical manner indicating a view of the second set of graphical elements through a port-region in the at least the portion of the envelope corresponding to a port into the bodily cavity, the plurality of graphical elements graphically displayed in a second distribution corresponding to the first spatial distribution.
