An example on how to implement the simple relu_plot_lib Plot in the video above is shown below. This code is available in the examples folder as well.

Plot(
  xTicks: Ticks(
    pretty: true, 
    logarithmic: true,
    unit: 'Hz',
    fractionDigits: 1,
    ),
  yTicks: Ticks(
    pretty: true, 
    unit: 'dB'
    ),
  graphs: [
    Graph(
      x: List<double>.generate(10000, (i) => i + 1.0), 
      y: List<double>.generate(10000, (i) => i + 1.0),
      color: Colors.blue,
      crosshairs: [
        Crosshair(
          width: 120,
          label: 'Crosshair', 
          yPadding: 20, 
          color: Colors.red,
        )
      ],
      annotations: [
        Annotation(
