JointJS is a tested and proven JavaScript/Typescript diagramming library that helps developers and companies of any size build visual and No-Code/Low-Code applications faster and with confidence. It’s a flexible tool from which a wide range of UIs can be created (interactive diagramming applications, drawing tools, data visualizations, UIs for monitoring systems, and many more). It can become the foundational layer of your next application and help you bring your idea to market in days, not months or years.
Further information, examples and documentation can be found at jointjs.com.
