For huge data input on coordinate system with a computer with low memory,disk etc. which programming language is useful with which algorithm? What would you offer?

This seems like too general a question. There are many, many TSP algorithms suitable for different purposes, and they can be implemented in many different languages.
If you in practice need to solve large graphs heuristically, I would use one of the existing packages rather than implementing your own, because it’s pretty non-trivial to implement a good heuristic solver. LKH is a state-of-the-art solver, I believe (free for non-commercial use). If you’re doing it more for education, you might be interested in Peter Norvig’s Jupyter Notebook walkthrough.
