Data is everywhere and so too is the visualisation of it. Every day I see weird and wonderful representations of complex data patterns that are used to help us understand or connect to the insight. It's this emotional element that I find fascinating. Good quality Data Visualisation has the ability to make its point viscerally without the need to explain the underlying algorithms, which I'm sure are equally as stimulating, if your brain works that way.
The visualisation of data (that is, the visual representation of data in charts and graphs) is seen as one way of addressing and overcoming these dangers, and of promoting data transparency and awareness. This is because the main way that people get access to data is through visualisations, which, like the data on which they are based, are also increasingly widely circulated. For a long time, experts have argued that visualisations are important tools for making data transparent and for communicating in ways that data themselves cannot.
