an object with keys dtype, bdata, and optionally shape. In this 3rd form, dtype is one of f8, f4. i4, u4, i2, u2, i1, u1 or u1c for Uint8ClampedArray. In addition to shorthand dtype above one could also use the following forms: float64, float32, int32, uint32, int16, uint16, int8, uint8 or uint8c for Uint8ClampedArray. bdata is either a base64-encoded string or the ArrayBuffer of an integer or float typed array. For either multi-dimensional arrays you must also provide its dimensions separated by comma via shape. For example using dtype: f4 and shape: 5,100 you can declare a 2-D array that has 5 rows and 100 columns containing float32 values i.e. 4 bits per value. shape is optional for one dimensional arrays.
Plotly.NET's API is statically typed and currently uses sequences of #IConvertible for these fields. This was a clever trick because this allows setting any of the CLR runtime types Boolean, SByte, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Single, Double, Decimal, DateTime, Char, and String while also making it very easy to serialize.
The new way of setting data_arrays seems to have speed advantages, and is therefore worth to be supported well from our side. A straightforward way of implementing this in the API providing a new type, e.g.
this type would also need functionality to encode the base64 string in a way that is understood by plotly.js. Maybe the python implementation's codebase can help here, as they seem to implement these functions as well.
Due to these large changes that also must be reflected on the CSharp lib, support for plotly.js >= v2.28.0 will be moved to the major release of Plotly.NET 6.0

Alternative: implement a really basic version of this first that offloads base64 encoding, shape, and datatype selection purely to the user and just provide the EncodedTypedArray type and overloads for the API taking these as alternative arguments for data.
This way, it would be possible to add this to v5 or a minor release of v5.
https://github.com/plotly/plotly.js/releases/tag/v2.28.0 introduces an option to set objects for encoded typedarrays for basically all fields that provide data to traces (e.g.
