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.
By using colour and an insightful title, we can focus our audience’s attention to a key take-away.
Through employing some storytelling techniques, including choosing an appropriate chart type, strategic use of colour and size and removing confusing or complicated elements we can enhance the focus of our data story.
There are a range of benefits that data visualisation can bring to help the public sector make better decisions. However, the type of visualisation we build depends upon the audience.
Data visualisation can help unlock hidden trends through use of colour or insightful titles for example. This insight can be used to inform decision making before it is too late.
