Gartner's 2018 Take on Data Science Tools

I've just updated The Popularity of Data Science Software to reflect my take on Gartner's 2018 report, Magic Quadrant for Data Science and Machine Learning Platforms. To save you the trouble of digging though all 40 pages of my report, here's just the new section: IT research firms study software products and corporate strategies, they survey customers regarding their satisfaction with the products and services, and then provide their analysis on each in reports they sell to their clients. Each research firm has its own criteria for rating companies, so they don't always agree. However, I find the detailed analysis that these reports contain extremely interesting reading. While these reports focus on companies, they often also describe how their commercial tools integrate open source tools such as R, Python, H2O, TensoFlow, and others.
