- - - - The Principle of Proximity states that we perceive
        objects that are located near one another as belonging
        to the same group
    - - The Principle of Similarity states that we perceive
        objects share some visual attribute as belonging to the
        same group
    - - The Principle of Enclosure states that objects that are
        enclosed by a visible border are perceived as belonging
        together
    - - The principle of closure asserts that humans perceive open structures as closed, complete or regular when we can reasonably do so
    - - The principle of
        continuity asserts that humans
        perceive objects as
        belonging together if they are aligned with one another
    - - States that we perceive
        objects hat are connected in
        some way as belonging to the
        same group.
        Grouping produced by connection is
        stronger than that produced by proximity or similarity
        (colour, size and shape)
- - - - A. Eliminate all unnecessary non-data pixels
        
        Eliminate graphics that provide nothing but decoration
        
        Variations in color that don't encode any meaning
        
        Unnecessary borders around sections of data fragment the display
        
        Unnecessary fill colors to separate sections of the display are distracting
        
        Gradients of fill colour both on the bars and background add distracting non‐data pixels
        
        Grid lines in graphs are not useful
        
        3D should be avoided when the added dimension of
        depth doesn't represent actual data
      - B. De-emphasize and regularize the non-data pixels that remain
        
        Axis lines and grid-lines can be useful but should be muted
        
        Navigational controls should not take up more space than the actual displays
        
        Instructions take up valuable space. They can be displayed only when needed through a separate screen or popup menu
    - - A. Eliminate all unnecessary data pixels
        
        Removing less relevant data
        
        Condensing data through
        
        summaries
        
        expections
      - E. Highlight the most important data pixels that remain
        
        Layout of dashboard should not change dynamically
        
        Different regions of a dashboard has different degrees of visual
        emphasis
      - B. Multi-foci displays
        
        Display more details for recent data and less for more distant data
      - C. Information that is always important can be emphasized
        using static means
      - D. Information that is only important at the moment requires
        a dynamic means of emphasis
- - - - Find the story first: explore the data
      - Determine what you want people to do as a result
      - Write out the “story board” for your audience
    - - Make it personal/emotional
      - Start with metaphor or anecdote
      - Develop with data: Authenticity is rooted in facts and
        facts are rooted in data
    - - Use graphs, charts, pictures when possible
      - • Design your graphs for instant readability but allow for layers of meaning as the graph is studied
      - • Use descriptive title, captivating images to get the point across
      - • Apply the design principles you learn.
      - • When designing infographics, include the subject’s theme into the design and display itself.
    - - Telling a story should be simple and direct. Recall and action will be that much stronger
      - • Stick to 2 – 3 key issues and how they relate to your audience
    - - Focus on highlighting what the audience needs
      - • Highlight key facts that relate to the story
      - • Extend the story parameters into questions
      - • Invite audience to continue the discussion via group discussion, blogs, intranets, newsgroups
