What are the x and y axes mean in Data Explorer view

I wanted to know the x and y axes of the Data Explorer about what value it represents. My professor asked me and I cannot answer.

I have read this documentation part about data explorer and I still cannot find the answer I wanted.

Hi @grindarius,

The axes don’t have a physical representation as we use some dimensionality reduction algorithm to represent N-dimensional data into 2D space. You can get more details in our documentation.
