I recently wrote a whitepaper for IBM on ways in which visualization can be used to effectively understand big data.  Obviously, that’s a “big” topic.  For this whitepaper I focused more on the complexity of big data than on the sheer scale, and on the ways in which visualization can be used to capture complex facets of the data in a “Customer 360” scenario where an organization may be looking to get a more complete picture of various aspects of their customers including time, social networks, key social influencers and customer relations.  It starts out with a simple stacked bar chart, and builds from there to increasingly complex visualization examples.  The whitepaper is available @ ibm.biz/bigdatavis.
