SAS Visual Analytics Collaboratory
Welcome to the VA web site - enjoy the visuals!
Abstraction and Creation
Is abstract art in any way resembling visual analytics?
Indeed, both are seeking some representation of reality, both are distorting the reality, both whe finally framed and exhibited are offencive to both the creator (for losing the intended message) and the public (for misunderstanding the artist).
Communication and Collaboration
The role of the visual analyst is to build bridges between the data and problem domains, which represent knowledge, experience and intuiton of two communities, i.e. the problem owners and problem solvers, who communicate in two distinct languages - the language of business and the language of data. A challenge!
Emergence of Insights
Beauty of visual form is an important element of visual analytics. It is important because of the very nature of human cognition which allows us to recognise beauty where there is order, a pattern or symetry and thus the likelihood of gaining insights is significantly greater.
Colour and Form
We are told that choice and the number of colours and forms to represent visualised information is of penultimate importance to the analyst. While these two aspects are of great importance, it is often understood that visual images need to be kept as simple as possible by means of as few as possible colours and shapes. This is a pitfall in those cases when the problem complexity needs to be shown complex to be fully understood.
Clarity of information visualisation allows clarity of perception and clarity of insights. However, when the prpblem representation is inaccurate and misrepresents the problem at hand that clarity is a great danger as gives a false feeling of true insights and leads to erroneous decisions.
How difficult is it to depict noise accurately? Visualised noise must not form patterns and ideas in the perceiver's mind - is this possible?
