How to build my own dataset?

[iostream1000]

I noticed that you used a self built dataset. I want to build a dataset in this format. What should I do or what tools should I use to mark it? Please give me some advice.

You could take this issue #14 and #57 as references. Additionally, the pt1 branch may show a clearer data structure [https://github.com/YueLiao/PPDM/tree/pt1/src/lib/datasets].
