So in my last blog, I briefly explored the proliferation of data, and examined how humans interact and process all this information. Going on to explore how data visualization has emerged as people seek to find ways to interpret complex information and translate it into a format that is easily understood.
This week I dove into the topic of data visualization more methodically, in the aim to answer this question: “What is data visualization, and why does it matter?” In this I examined the historical and academic origins of the practice; examine its use in society and lastly explored and analyzed key examples of data visualization.
While some might think that data visualization is a new concept, and only emerged with the introduction of Web 2.0, computers and developments in statistics. In actuality, graphic representation of quantitative information has deep roots. According to historian Michael Friendly (2006 & 2008) it dates back historically to “early map making and visual depiction, later into thematic cartography, statistics and statistical graphics, medicine and other fields.” Friendly goes on to state that due to developments in technologies (namely printing and reproduction), mathematical theory and practice, and empirical observation and recording, has enabled a wider use of graphics thus leading to new advancements in form/content analysis and interpretation.
While it’s longstanding historical documentation and application in multiple fields might suggest its importance, academics suggest its value lies in the medium’s ability to summarise large amounts of complex data in a format that is universal and easy to understand (Few 2007, p. 9). Just how do we end up with beautiful pieces of data art, what process do these visualisation experts go through to create these data masterpieces. Data visualisation expert Ben Fry in his book ‘Visualizing Data: Exploring and Explaining Data with the processing Environment’ breaks down the process into a series of steps:
Acquire, Parse, Filter, Mine, Represent, Refine, Interact (Fry 2008, p.7)
I aim to follow these steps during my own creation of a piece of data visualisation, and document the challenges and my thinking at each stage. So look for the next blog where I explore the ‘Acquire’ step and share some amazing resources that I have found, while exploring the issues such as data storage, access and privacy.
In the meantime, feast your eyeballs on some of the diamonds that has emerged from the data mining and refining process. Click (hyperlinked title above image) and explore. Your welcome.
