Is there a quick way of obtaining the graph of D functions like these?

T f(T) if (isScalarType!T){}

or

T[2] f(T, T)if (isScalarType!T){}

I know that there are graphing calculators already, but these don't support low level black magic like int <-> float conversions and i'm lost because there is no way to know if the code i write is correct without a graph or trial and error, hence the question.

Many thanks

Probably the easiest way would be to run the function on a bunch of different inputs, and plot the input-output pairs as 2D or 3D points. Pretty much any plotting software should be able to handle a list of points.

I'm not that familiar with D libraries, but I'm sure there is a graphing library. If not, I will make one soon because I need one. If you just need a graph, write a loop calling that function and print input, output to a file (csv) Then put it in google sheets or excel and make a graph.
However, what I would do to determine if the function is correct is look at the output in the console then write unit tests.
