Week 3 Aftershocks....
What are "core skills" for visual analytics?
In my view, the "core skills" are the abilities to "see" patterns through mental framing of the data, horned and sharpened through countless of practices and manipulation of data.

Learning to build the interactive dashboard was an interesting takeaway from the session this week. One learned that R was not able to do the interactive visualization which Tableau could. And while Tableau could provide interactivity to some good extent, D3.js appears to be the way to go. However, what I was not very certain was that if good visualization should equate to being 'fanciful' and having that 'wow' factor, as we see in what D3.js could do. My view is still evolving in this space.

With the interactive design, it allows us to better explore and analyze data according to the mantra from Ben Shneiderman, "Overview first, Zoom and filter, then detail on demand". I've the example when we're analyzing online marketing campaign performance. We've to start with overview of the month i.e. How much revenue we've got and what's the ROI. Next, we'll zoom and filter into each channel or specific campaign. Also, there are sometimes we'd want to drill down on details such as which SKU sold we from the best performing email newsletter (EDM).
