### Method
A basic chart was used with a scale from 0-100 for simplicity.
Setting the `AXDataSeriesDescriptor` `isContinuous` value to `true` will play the graph curves, what we want is discrete notes, so we set this value to `false`.
Using [Piano Key Detector](https://apps.apple.com/al/app/piano-key-detector/id1612601920) app, the discrete sounds were mapped to music notes across intervals of `5`.
```Swift
// .init(time: 0, value: 0), // C5
// .init(time: 1, value: 5), // D5
// .init(time: 2, value: 10), // D5
// .init(time: 3, value: 15), // D#5
// .init(time: 4, value: 20), // E5
// .init(time: 5, value: 25), // E5
// .init(time: 6, value: 30), // F#5
// .init(time: 7, value: 35), // F#5
// .init(time: 8, value: 40), // G#5
// .init(time: 9, value: 45), // G#5
// .init(time: 10, value: 50), // A#5
// .init(time: 12, value: 55), // A#5
// .init(time: 13, value: 60), // B5
// .init(time: 14, value: 65), // C6
// .init(time: 15, value: 70), // C#6
// .init(time: 16, value: 75), // D6
// .init(time: 17, value: 80), // D#6
// .init(time: 18, value: 85), // E6
// .init(time: 19, value: 90), // F6
// .init(time: 20, value: 95), // F#6
// .init(time: 21, value: 100) // G6
```
Once the notes were identified, a simple version of Clair de Lune was found, https://www.youtube.com/watch?v=ra08MiW8jLw
This was manually mapped to the music notes identified above, with pauses in the song where appropriate.
