  • Data Art is what gets more interest from the general media because it’s aesthetically beautiful, and looks good in coffee table books like Information Is Beautiful, but data visualisation is of more interest to us, because that’s actually more about the story in the data rather than the beauty of the presentation, so the focus is on leaving the reader understanding rather than appreciating.Data Art actually works against the principles of open data – because it requires specialist, technical skills, it remains in the hands of the few, and there is far too much data publicly available for those few to represent it all pictorially.
  • In 1983 data visualization aficionado Edward Tufte published his groundbreaking book The Visual Display ofQuantitative Information, which showed us that there were effective ways of displaying data visually and then there werethe ways that most of us were doing it, which were sadly lacking in effectiveness.
  • Data visualisation is essentially the simplification of information, so that it becomes easier to read, with key findings easily identified.It’s not something she’s primarily associated with, but Florence Nightingale was an early exponent of data visualisation, collecting data on army deaths during the Crimean war, and visualising them with this polar-area diagram. For each month (Year 1 on the right, Year 2 on the left), it shows deaths from battle wounds (red area), deaths from preventable diseases (blue) and deaths from other causes (black). It clearly shows how cholera, typhus and dysentery were killing far more soldiers than Russian artillery, and was enough to convince Army generals that sanitary field hospitals were a necessity of modern warfare.

    1. 1. Data Visualisation
    2. 2. “I keep saying the sexy job in the next ten years will be statisticians.” The ability to take data - to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it is going to be a hugely important skill in the next decades, not only at the professional level but even at the educational level for elementary school kids, for high school kids, for college kids. Because now we really do have essentially free and ubiquitous data. So the complimentary scarce factor is the ability to understand that data and extract value from it.

    7. 7. Data Visualisation = Infographics
    8. 8. Data Visualisation = Data Art
    9. 9. Data Visualisation Data Art Purpose To inform/enlighten To entertain/delight Objective Simplify the data Beautify the data Desired response “That’s informative/ interesting/ illuminating” “That’s beautiful” Proponent Hans Rosling David McCandless Creator PLANNERS CREATIVES
