Information visualisation is a general term that refers to using tables, graphs, maps, and even text, whether static or dynamic, to “provide some means to see what lies within, determine the answer to a question, find relations, and perhaps apprehend things which could not be seen so readily in other forms”.  Data visualisation is defined as “information which has been abstracted in some schematic form, including attributes or variables for the units of information.”  (Michael Friendly, 2009)

Andy Kirk provides a list of essential visualisation resources on his blog.

On the Improving Data Visualisation for the Public Sector Project webpage by the Department of Communities and Local Government and the Oxford Consultants for Social Inclusion (OCSI),  some useful resources also are recommended.
