After posting Machine Learning Summarized in One Picture, here is a picture for data science:

I tried to find the source for this picture, but could not. I've found it on LinkedIn, posted by Mathias Golombek, CTO at Exasol. This picture was also spotted here

Are there any components that you would add? I would definitely add automated data science (machine-to-machine or device-to-device communications, automated transactions such as algorithms that automatically purchase keywords on ad networks.) This article also helps clarfy what data science, machine learning, automation, algorithms and data architectures are about.

@ Scott Mongeau - it would be great if you could expand on your description of what "Visualization" means here, and maybe expand just a little on why it is floating up there off the main trail. I note that others have enjoyed the diagram, but never succeed in addressing this question: https://www.upgrad.com/blog/data-science-summarized-in-one-picture/

Looks like a version of my representation from 2013/14 teaching/consulting/blogging.  Indeed a simplification (Box's "all models are wrong, but some are useful" principal ;-)): 


Some useful additions have been made.  I generally use this in teaching during introductory lectures, or to orient clients with little analytics / data science background or context.

Managers and decision makers who know little about data science need a place to start their education and this visualization is a start. I agree with Paul McLeod that it fails to tell the whole story but that in my view is not a failure of visualization, as I think his comment suggests.

Systems architects have the same challenge in explaining their craft and illustrating the complex constructs that make up their world. From what I have seen they have developed numerous visual representations that do the job remarkably well.

I would challenge data scientists to find ways to transcend the world of algorithms and make their insights more accessible to the unwashed masses.

I think this is a very popular oversimplification.
Visuals do allow powerful but biased wetware to engage on decisions, but only to take in a limited number of factors.

To work with large/vast sets of variables, visualization is feeble. Algorithms rule.

Also th focus on understanding, popular as it is, runs as a distraction to building the best engine for making the optimal decision.

I'd add Network analytics, Supervised/Unsupervised, Propensity, Recommendation, Preference Analytics, Identity/Identification Entity Analytics and with Understanding probably add a point for Hypothesis Testing, to differenciate.

Also I'd cover A/B testing, Deployment, Decision Modeling, Optimization/Trade-off, Champion/Challenger and Realtime-scoring.

Surely space on data preparation,munging,feature engineering, discovery,tuning, and information flow are important. And then you get to data engineering and modeling.

All this makes the picture complex and perhaps overly complex, but I believe it is just now overly simplistic and populist. As it stands, this is probably fairly accurately showing the common stereotype of Data Science, rather than its fullness.
