    Is there a way to build an interactive node graph in JavaScript? - Stack Overflow

    programmeradmin3浏览0评论

    I'm looking to build an interactive node graph on a webpage where you can add nodes with various inputs and outputs and connect them together.

    This is an example of what I'm looking to do:

    I started to play around with vis.js but I'm not sure it will be able to do the above.

    Any suggestions would be appreciated!

    • javascript
    • graph
    • vis.js
    • vis.js-network

    • Have a look at d3.js as an alternative - refer to the 'Examples' link as well as here for examples. – trashr0x Commented Aug 12, 2018 at 0:37

    For those who (like me) trying to find js libraries for creating interactive graphs here is the list:

    Click on images for better quality.

    react-flow | demo

    vis-network | demo

    DAG-ToDo | demo

    flowy | demo

    jsplumb | demo

    react-diagrams | demo

    butterfly | demo

    Drawflow | demo

    Generally, such broad questions in form of "is it possible to ...?" are frowned upon at StackOverflow, but the direct answer would be "yes, it is possible" and moreover, vis.js has an example of a manipulatable graph so I remend you to read the manupulation methods docs and the manipulation module docs which describe methods like addNode, editNode, deleteNode etc.

    However, you should note that all the interfaces are usually implemented outside the graph-containing canvas, in html (+js) because it's not trivial to put them inside canvas and, say, show attached to all nodes.
