    // 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
