Interactive visualization application entry point (placeholder).

This module is reserved for a future interactive front end (for example a
GUI or web application) that orchestrates `relatipy` visualization workflows.
Plotting helpers live under :mod:`relatipy.visualization._2D` and
:mod:`relatipy.visualization._3D`.

The module currently defines no public API. Extend this file when adding an
application entry point or shared app configuration.
