We are one step closer to becoming a map data scientist. We covered a lot of ground in this chapter, starting with a brush up of a few introductory statistics concepts. We then saw the code in action in how a statistics definition and feature layer statistics module can give us invaluable statistic measures that can be used to render the map data meaningfully. We then evaluated how to use the visual variables such as colorInfo, opacityInfo, rotationInfo, and sizeInfo effectively in a renderer. We also tried to combine these visual variables and performed a multivariate rendering. And, finally, we tried our hands at automatic rendering using the smart mapping module. In the next chapter, we will be dealing with charts and other advanced visualization techniques to provide analytical information to the users.
