Adding meaning to the legend
For this map displaying agro-ecological zones, we changed the colours to reflect the organization of the different zones. We then designed the legend in a grid that captures the nature of the zones in terms of their environment, humidity and growing period.
The reader can now quickly grasp how each zone relates to another. Additionally, even when the reader may not be able to distinguish between two similar colours, the added information below the grid lets them understand a zone’s environmental characteristics.
