// A graph's display properties (marker symbol, axis characteristics, and 
// so on) are general properties that are defined in the graph's model. The
// marker characteristics are defined as MarkerStyles that are applied to
// the plot's DataElementStyles. Thus, the change the markers,
//    1) Get the LineChart's model
//    2) Disable interpolation and enable plot markers
//    3) Define a MarkerStyle for the plot markers
//    4) Set the MarkerStyle on the model's DataElementStyles
