In this chapter, we explored the random walk simulation and how to communicate through animated visualizations. Simulation is an excellent way to see certain behavior of a phenomenon such as stock prices. The Monte Carlo methods are widely used to simulate phenomena when we don't have the means to reproduce an event because it is either dangerous or expensive such as epidemic outbreaks or stock prices. However, a simulation is always a simplified model of the real world. The goal of the simulation presented in this chapter is to show how we can get a basic but attractive web-based visualization with D3.
In the next chapter, we will learn the basic concepts of time series. Then, we will present a numeric prediction of gold prices using regression and classification techniques.
