Solution

The arbitrary approach with which the panel displayed large amounts of often seemingly unrelated information was completely thrown away. 



Many changes were made so that the panel was now showing only that information, that was directly connected to the metric currently being visualized in the map. While this reduced the possibility of displaying “related” and “useful” information next to each other, it was finally unambiguous what is being displayed and made the information consistent.

Great deal of development effort was devoted towards making sure that any element in the panel or any object in the map was fully interactive. This finally enabled that any action in the panel was now directly followed by a logical reaction in the map and vice versa.

Addition of highly contextual and interactive legend dramatically improved the understanding of the map and careful cartographic redesign of the base map improved legibility of visualisations.
