We have seen how the human brain processes visual information through iconic, short and long term memory. Pre-attentive attributes such as colour, length and position are visual properties that are processed very quickly in the sub-conscious memory. As data visualisers we can leverage pre-attentive attributes to focus our audience’s attention to highlight key performance issues.
Colin was proactive in researching and incorporating best practice data visualisation techniques and applying them in his dashboard designs. He was keen to engage with business stakeholders, communicating the art of the possible and listening to their feedback.
Building different views allows our audience to see different insights from the same data. This means being able to quickly ask and answer business questions. This is important to be able to see the underlying cause of problems. It also means that we can go exploring in detail different paths of analysis, which is a great way to engage our audience’s curiosity.
Quite often we will see data visualisations which try to stand out by using too much colour. The problem is that this can lead to cognitive overload as there is too much to process. Additionally when everything is the same colour then nothing really stands out.
