// A graph's display properties (marker symbol, axis characteristics, and 
// so on) are general properties that are defined in the graph's model. The
// line style for an interpolated line is defined as a StrokeLineStyle that
// is applied to the plot's DataElementStyles. Thus, to change the line style,
//    1) Get the LineChart's model
//    2) Define a StrokeLineStyle for the plot markers
//    3) Set the StrokeLineStyle on the model's DataElementStyles
