In an era increasingly defined by the proliferation of big data and its transformative impact on decision-making across disciplines, the ability to interpret and engage with complex datasets has become an essential skill for future generations.

By framing data visualisation as both a product and a process, the paper explores how data visualisation be utilised in activities framed within the context of self-quantification.
