Automatic position for nodes

[LucasLopesr]

Hi, I'm looking for a simple library to create a diagram and I'm very interested in using Drawflow.

I have a question, if I import data without a position definition for the nodes, does Drawflow organize or assign an automatic position?

if not, how complex would it be to add this?

The import has to have the value pos_x and pos_y.

As it's shown in the following:

{
    "drawflow": {
        "Home": {
            "data": {}
        },
        "Other": {
            "data": {
                "16": {
                    "id": 16,
                    "name": "facebook",
                    "data": {},
                    "class": "facebook",
                    "html": "\n        
\n          
 Facebook Message
\n        
\n        ",
                    "inputs": {},
                    "outputs": {
                        "output_1": {
                            "connections": [
                                {
                                    "node": "17",
                                    "output": "input_1"
                                }
                            ]
                        }
                    },
                    "pos_x": 226,
                    "pos_y": 138
                },
                "17": {
                    "id": 17,
                    "name": "log",
                    "data": {},
                    "class": "log",
                    "html": "\n            
\n              
 Save log file
\n            
\n            ",
                    "inputs": {
                        "input_1": {
                            "connections": [
                                {
                                    "node": "16",
                                    "input": "output_1"
                                }
                            ]
                        }
                    },
                    "outputs": {},
                    "pos_x": 690,
                    "pos_y": 129
                }
            }
        }
    }
}

You could transform the positions before importing. I don't think it's very complete. Depending on the type of diagram you want to create.

Another option is to move the nodes once assembled.

I got it.

Wouldn't it be interesting for the lib to automatically do this positioning based on the parents and number of children? Like this one:

For each new node added, its position would be recalculated based on the number of children, without the need for those who consume the library to say where on the canvas the node should appear

[jerosoler]

The library is intended for data flows not for diagrams. One thing is that it can be adapted.

Okay thank you @jerosoler
