Much information from models are relevant to review per region / license or fault block.
A generic private plugin to display these polygons will be useful.
This JS plugin is a good starting point: https://github.com/equinor/webviz-js-plugins/blob/master/webviz_js_plugins/_isochorethickness.py

• Decide on dataformat for polygon

• Well picks

• Selector for realization ( Polygons will differ if HUM updates velocities)

• Selector for zone / zonetop

• HoverData/Clickdata callback that returns selected polygon
