Heartcount makes it really easy to do EDA. I like the product on four points: 1) the automatic binning to create derivatives 2) the super easy drill-down 3) individual data visualization and interactivity of the smart plots 3) a variety of supported analytics to optimize KPIs. Driver analysis makes it easy to perform regression analysis, and I can try decision tree algorithms with the Micro-segment. I'm also a fan of the Difference analysis because I can easily find the differences in the statistical characteristics of two main groups.
