Basics of data visualisation - what it is, techniques, how to create visualisations, tools and software.

What is data visualisation?

Data visualisation is where visual means are used to communicate data. This visual representation can take many forms. A simple bar graph, generated in Excel, is data visualisation. More complex forms can include 3D models and map overlays. Visualisations can incorporate interactive elements which allow users to manipulate the data in various ways or to bore down into the data, enabling it to be queried and/or analysed.1, 2

Different tools can be used to create the visualisations. Some data analysis and programming languages include visualisation tools.
