Add a plot to showcase the validation of the grid.

For example, the plot could show 2 plots, such as:

• the reference network plot
• the network of the network under investigation

Alternative formulations are welcome :D

A great point and agree that it visualisation is crucial for the grid part. @GbotemiB given your experience, it would be great to have your inputs for this point.

Yeah. My experience with visualizing such plots with geojson/maps format, having the plots overlap with different colors on each other should be fine. This will make it easier to identify gaps in one view, without having to go back and forth between the networks.
