Converting CSV to Hierarchical JSON Output: A Step-by-Step Guide

In the world of data processing and analysis, converting data formats is a common task that many face. One such challenge is converting a CSV file, which is a simple table of data, into a Hierarchical JSON format that is structured and easy to read. This post will break down how to achieve this transformation using Python.

Understanding the Problem

Imagine you have a CSV file that contains two columns: Gene and Disease. The data might look something like the following:
