Add a way to redraw graph by supplying new data

[bittorf]

is it possible to read in an updated json-file without redrawing everything (avoiding the funny animation at the beginning)? e.g. delete or add 1 link.

I think it's possible, I'd love this library to be able to handle this feature nicely.

I would also love to allow avoiding the funny animation in the beginning!

In my pull-request, I introduced init(), reInit() and destroy() functions but perhaps a dynamic solution like web-socket could be more cool...

Nice animations can be reduced a lot just setting animationAtStart to false ;)

@geekplux we should definitely do this! Do you remember we discussed about it? I'm setting it for the second phase.

[nemesifier]

Let me clarify, I think we need to create a way to easily update the graph with a function/method or something like that, so we can update the graph as we get new data from a server.

[geekplux]

I see what you mean.

[nemesifier]

@geekplux great. Notice how different people asked for the same feature in #31 and #26. If you implement this feature we can implement it straightaway in django-netjsongraph, that would be nice.

at battlemesh10 we tried to have some kind of auto-refresh with 'animationAtStart = false' and this block:

around line 209:

 if(!opts.animationAtStart) {
            opts.linkStrength = 10;             // was '2'
            opts.friction = 0.0;                // was '0.3'
            opts.gravity = 0;
        }

but this is not enough, it still "jump" during every reload. see this example here: http://intercity-vpn.de/networks/giancarlo/meshrdf/netjson.html

@bittorf I've created a new issue regarding disabling the animation in https://github.com/netjson/netjsongraph.js/issues/42

[nemesifier]

@geekplux what's the status of this issue?

[geekplux]

done

[nemesifier]

@geekplux how can I test this?

[geekplux]

like this:

new Netjsongraph('url').load(newData).render()

[aparcar]

@geekplux is this actually implemented? I'm trying something like this:

        <script type="text/javascript">
            graph = new d3.netJsonGraph("/graph-json")

            function update_graph() {
                fetch("/graph-json", { method: 'GET' })
                    .then(res => res.json())
                    .catch(error => console.error('Error:', error))
                    .then(response => graph.load(response).render());
            }
        </script>

The graph object is just empty

@aparcar you can have a try to use my version which in develop branch and refactor folder
