How to Create a Unique JSON Object from a Pandas DataFrame

When working with data in Python, particularly in data science and analytics, you often need to convert data into different formats for analysis or presentation. One common task is converting a Pandas DataFrame into a JSON object. In this guide, we'll discuss how to create a unique JSON object that accurately represents the data in your Pandas DataFrame.

The Problem

You may encounter a situation where you have a DataFrame containing information such as home values over different years, and you want to convert this DataFrame into a specific JSON format. For example, given a DataFrame that looks like this:
