In my previous company I was tasked to build an app to display our company's employee structure but after I built it, my manager and didn't merge it, because of hate, and he got me fired few months after I built it, and now I have decided to build a better version of the project using D3js and fully object oriented TypeScript, it's a library for displaying organization structure in style and in simple steps, it has different tree types that can be chosen from and the one that fits into your organization design and it is also highly customizable.
