1. A method of visualizing price history of a stock index in an animated graphical representation, the method comprising: (a) generating, using a processor, a dataset for a set of stock index closing prices adjusted by (i) a macroeconomic indicator, and (ii) a time lag, wherein the dataset includes a plurality of data points, each data point being an observed adjusted closing price of the stock index; (b) selecting, via a user interface, a time period of the price history to be visualized and electronically communicating the selected time period to the processor, wherein the selected time period has a plurality of segments, and each segment of the time period is distinguished by a different color and the data points are assigned a color based on their respective segment; (c) providing a histogram on a display screen, the histogram having: (i) an x-axis representing the adjusted closing price of a stock index, and (ii) a y-axis representing the frequency of occurrence for each of the adjusted closing prices; (d) animating the dataset in the histogram on the display screen using a datafall engine of the processor and the selected time period so that each data point appears at the top of the histogram at its x-axis value as a unique symbol which is then animated to fall in a straight line towards the bottom of the histogram, wherein each data point appears and falls in chronological order from the oldest data point to the most recent data point, the most recent data point being represented by a unique symbol that is visually distinct from the other data points in the dataset, each data point for the same x-axis value piling on top of an earlier data point; and (e) constructing a frequency distribution histogram of the data points via the animation which visualizes the price history of the stock index in an animated graphical representation, the most recent data point being represented in the frequency distribution histogram by the unique symbol that is visually distinct from the other data points in the dataset.
