Investigating d3-axis code to fix date format issue.

Story

Description

As a developer, I would like to extend my investigation on the date format issue to go through the d3-axis code.

Motivation

So that we can suggest changes to the d3 team to fix the date format issue in terra-graphs

Definition of Done

We'll know we're done when we come up with suggested changes to fix the date format issue.

Based on the investigation I have done, when null is passed as tickFormat, d3 determines the format based on tick values consumer provides using this code. Since [this logic] renders (https://github.com/d3/d3-scale/blob/main/src/time.js#L20-L37) irrespective of locale, we are seeing the same format in Carbon for every locale we use, which leads to date format internationalization issue.

To fix this issue, d3 format selection needs to be locale-specific, but the d3 team is not ready to do these changes(which you can see in this comment). So this will leave us with building our own logic based on axis limits provided by consumers to fix the date format issue.
