  We give emphasis on the use of chaos-based rigorous nonlinear technique
called Visibility Graph Analysis, to study one economic time series - gold
price of USA. This method can offer reliable results with fiinite data. This
paper reports the result of such an analysis on the times series depicting the
fluctuation of gold price of USA for the span of 25 years(1990 - 2013). This
analysis reveals that a quantitative parameter from the theory can explain
satisfactorily the real life nature of fluctuation of gold price of USA and
hence building a strong database in terms of a quantitative parameter which can
eventually be used for forecasting purpose.
