Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine The holy trinity of the reader, data and designer Noah Illiinsky and Julie Steele in ‘Designing Data Visualizations’

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refineEXPLORE: facilitate reasoning of data EXPLAIN: convey information to others Analysis Answer questions/Inform Familiarise with data Learn/Increase knowledge Support graphical calculation Contextualise data Find patterns/Find no patterns Present arguments Discover questions Assist with decisions Interact Shape opinion Persuade Emphasize issues Tell a story Inspire Shock/Make an impact Enlighten Change behaviour Entertain Art/Aesthetic pleasure

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine What questions are you hoping to answer through this visualisation? What questions should users/readers be able to answer through this visualisation?

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine We’re so busy thinking about if we can do things we forget to consider whether we should Amanda Cox, Graphics Editor, New York Times http://eyeofestival.com/speaker/amanda-cox/

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine Original – J. D. MacKinlay, “Automating the design of graphical presentations of relational information”, 1986 | Redesign - Joe Parry

Purpose and Formulate Familiarise Develop Construct Evaluate and parameters questions with the data designs visualisation refineThe data layerLayout, placement and apparatus - Reduce cognitive overhead - Consistency/intuitive layout - Meaning behind placement and arrangement - Minimise impact of chart apparatusColour and backgroundAnimation and interactionThe annotation layer

Purpose and Formulate Familiarise Develop Construct Evaluate and parameters questions with the data designs visualisation refineThe data layerLayout, placement and apparatusColour and background - “Above all, do no harm” – Edward Tufte - Use colour to enhance and clarify a design - Don’t obscure, shout or confuse with colourAnimation and interactionThe annotation layer

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine The eye is only able to distinguish about 8 different colours http://www.flickr.com/photos/walkingsf/6276642489/sizes/l/in/photostream/

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine Background colour should help enhance the foreground data layer

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine Blue on black is not very easy for some people to discriminate ...and neither is yellow on white for most ...and don’t forget red/green colour blindness (10%)

Purpose and Formulate Familiarise Develop Construct Evaluate and parameters questions with the data designs visualisation refineThe data layerLayout, placement and apparatusColour and backgroundAnimation and interaction - Remember the purpose/parameters - Technical constraints and capabilities - Complexity of data/problem frameworkThe annotation layer

Purpose and Formulate Familiarise Develop Construct Evaluate and parameters questions with the data designs visualisation refineThe data layerLayout, placement and apparatusColour and backgroundAnimation and interaction - Variable adjustment - View adjustment - Animation - Import/export dataThe annotation layer

Purpose and Formulate Familiarise Develop Construct Evaluate and parameters questions with the data designs visualisation refineThe data layerLayout, placement and apparatusColour and backgroundAnimation and interactionThe annotation layer - Titles, labels and units - User guide, background, context - Legend/key - Headlines, captions and narrative - Sources

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine The annotation layer is the most important thing we do... otherwise it’s a case of ‘here it is, you go figure it out’ Amanda Cox, Graphics Editor, New York Times http://eyeofestival.com/speaker/amanda-cox/

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refine ...you’ve started playing with thevisualization instead of debugging ... you hit some level ofengagement and it becomes really interesting Martin Wattenberg, "Big Picture" data visualization group, Google http://queue.acm.org/detail.cfm?id=1744741

Purpose and Formulate Familiarise Develop Construct Evaluate andparameters questions with the data designs visualisation refineYou know you’ve achieved perfectionin design, not when you have nothing more to add, but when you have nothing more to take away Antoine de Saint-Exupery
