I've added a new example of combined use of autodif, fit, kmath-for-real and visualization features: https://github.com/mipt-npm/kmath/blob/dev/examples/src/main/kotlin/kscience/kmath/commons/fit/fitWithAutoDiff.kt. I will refactor kmath-for-real a little bit more so one can get almost numpy-like experience with it and then prepare for the release.
