cl-ana VS cepl

I understand what you mean; but despite CL appearing as a very similar to EL, the trouble would be probably significant due to missing libraries and semantic differences between CL and EL, in case of any significantly sophisticated plotting library, such as cl-ana for example. It is probably easier to port Emacs to CL, than that thing to Emacs :).

There are some other active Lisp efforts in the data science space, such as cl-ana.[1]

If you like spreadsheets, you may appreciate the Cells library. I haven't used it myself yet, however it is billed as "Spreadsheet-like expressiveness for CLOS, the Common Lisp Object System." I believe cl-ana also implements some spreadsheet-like functionality. This article demonstrates some trivial usage of Cells.

cl-ana - Common Lisp data analysis library with emphasis on modularity and conceptual clarity. It aims to be a general purpose framework for analyzing small and large scale datasets, including binned data analysis and visualization. [GNU GPL3][2].

CEPL is great for something more advanced.

https://github.com/cbaggers/cepl There are a lot of videos of this being used, link is in the project's README.

I used to write software for image generators using GLSL and so I used to do some graphics projects using C, OpenGL, and GLSL. Later I discovered CEPL, which gave me a REPL to do GLSL-like graphics pipelines. That was an improvement but I don't find GLSL fun. But then I discovered April and APL in general and now I can dabble with image processing whenever I feel like it with minimal ceremony.

If I was doing a course in computer graphics today I would sidequest with April and CEPL.
