Get some advice on how to handle this. I know plenty of lawyers who'd gladly spend a few minutes listening to your story and giving you some "unofficial" advice (by that I mean that unless you actually pay them, they won't write a letter or represent you - you're stuck implementing that advice yourself.) I'd wager this was a threat from an immediate manager. Go over his head. Explain you did this as coursework. Have someone explain the company's view of these "similarities" - Just because their app sorts entries in a table on an iPad doesn't mean publishing that sort.js you built in class is an IP problem. See if they'd be willing to generate some goodwill amongst the OSS community by allowing you to put chart.js back online. DO NOT SIMPLY ROLL OVER. And if you get stonewalled, these are probably not the kind of people you want to work with. Start looking for a new job. Don't fear for this one. Programmers, developers, software engineers (pick your flavor) are in high demand.
