When we receive an idea, we try to make sense of it by categorising the parts we recognise and putting it back together using images that already exist in our subconscious. If we are familiar with the concepts, the picture formed in our mind is clearer. If an idea is new or foreign to us, creating any kind of connection to it becomes much harder and more abstract. But when we can see the idea visually represented, it suddenly comes to life and removes the ambiguity.
The value of illustration lies in its ability to translate the abstract into something that we can connect with, giving shape to the unseen. In many ways visualisations make an idea more accessible. Depending on the type of visual - they can even make ideas more believable.
Take the art of cartography. When navigating space, we try to imagine the destination and create a path in our mind to help us get there. Our eyes can only see the limited space around us, just like a torch only lights the way a few steps ahead. We rely on memory, directions and our mind’s eye to fill in the gaps between where we are and the destination. Maps are a widely used graphic that gives us a bird’s eye view and allows us to clearly see the path we need to follow. . A cartographer needs to compile data and simplify it, omitting some parts and highlighting others in order to create a universal language that can be understood by the audience.
The ability to synthesise and curate data is central to the professional illustrator. In a pre-internet world, expertise was often about access to specific information which was commodified. Today the mark of expertise is not defined by access to information, but rather the curation of it. If we look at the surge in popularity around illustration, we will see that what drawing offers revolves around personal perspective. Drawings are curated ideas and information, distilled into the parts that matter most.
As a medium, Illustration is also incredibly flexible. It can be adapted to reflect brands, and can be highly impressionistic which imbues a concept with emotional sentiment. Unlike many other visual mediums like photography and film which often require a closeness to the subject; illustration is limited only by the imagination. You can literally create worlds from the comfort of your lounge sipping a cup of tea. This is why it is very valuable in prospective design, or when the concept visualised does not exist yet. It is an effective tool that helps ideas materialise and come to life.
Illustration can also break down barriers. A few years ago, I was part of a research project which centred around clinicians working in palliative care. Visiting patients at the end of their life was highly confronting, and taking photos was inappropriate. Drawing, on the other hand, was not only acceptable - it was encouraged. The results of this approach were quite incredible, and utterly unexpected.
Our minds are much more receptive to visual information than words; seeing an idea helps it become relatable, easily processed and understood. Through the process of understanding and analysing, we can then build on and iterate the idea. This is why visualisations are a vital tool in getting people to act, not just think.
