I'm trying to use a library called flowy which is a drag and drop flowchart but I'm having trouble outputting flowchart data from a data object.

I see on the github page

flowy.output();

and

flowy.import(output)

but I'm havimg trouble implementing.

Also how can I save a flow diagram that I create?

Thanks so much!

What I have tried:

I tried making a json object to import but I don't seem to get any blocks outputted. Here is a jsfiddle of what I'm working with.

flowy.import({
	"html": "",
	"blockarr": [],
	"blocks": [
		{
			"id": 1,
			"parent": 0,
			"data": [
				{
				"name": "blockid",
				"value": "1"
				},
        {
      "id": 2,
      "parent": 1,
      "connector": 2,
      "data": {
      "name": "block-id",
				"value": "2"
      }
    },
			],
			"attr": [
				{
				"id": "block-id",
				"class": "create-flowy"
				}
			]
		}
	]
})
