The document discusses different narratives of big data, including the four V's of volume, velocity, variety and variability; the rise of data scientists and predictive analytics; and machine learning tools like deep learning. It then argues that big data is essentially about storytelling, and discusses techniques like data visualization pioneered by Bertin, Tukey and Tufte. Finally, it presents some tools that can be used for data-driven storytelling, such as Google Correlate, Gephi and IPython notebooks.
