Has anyone come accross a JavaScript/jQuery based library that helps to annotate images with arrows?
Would be great for us to use in our project.
Have you tried djaodjin-annotate.js before? It should be exactly what your looking for,
djaodjin-annotate.js (Open Source)
djaodjin-annotate.js is a simple jquery plugin allowing you to annotate a screenshot.
If you are looking for a commercial product, the LEADTOOLS JavaScript libraries can definitely do this for you. There is an online demo that you can test out as well found here. Below you will see a screenshot of the demo with arrow annonations as well as other annotations that can be added:
If you are interested, you can evaluate the toolkit and make any modifactions you please. The free eval last for 60 days and includes demos as well as the source code.

Essential Diagram for JavaScript allows you to annnotate images. Simple sample application:link.
The whole suite of controls is available for free through the community license program if you qualify. Note: I work for Syncfusion.
We just released a developer library/api for annotation product Markup Hero. It's quite slick and easy to implement. Here is a demo of it in action with Notion (this is just a demo, Notion hasn't integrated it... yet). But we have a handful of SaaS companies integrating. Quite flexible and clean.
