/**
* This is the data that's coming through main chart `data` prop
* Recharts is very flexible in what it accepts so the type is very flexible too.
* This will typically be an object, and various components will provide various `dataKey`
* that dictates how to pull data from that object.
*
* TL;DR: before dataKey
*/
/**
* So this is the same unknown type as ChartData but this is after the dataKey has been applied.
* We still don't know what the type is - that depends on what exactly it was before the dataKey application,
* and the dataKey can return whatever anyway - but let's keep it separate as a form of documentation.
*
* TL;DR: ChartData after dataKey.
