Getting Started in Python

Prerequisites

Make sure that dash and its dependent libraries are correctly installed:

pip install dash

If you want to install the latest versions, check out the Dash docs on installation.

Usage

Install the library using pip:

pip install dash-cytoscape

Create the following example inside an app.py file:

import dash
import dash_cytoscape as cyto
import dash_html_components as html

app = dash.Dash(__name__)
app.layout = html.Div([
    cyto.Cytoscape(
        id='cytoscape',
        elements=[
            {'data': {'id': 'one', 'label': 'Node 1'}, 'position': {'x': 50, 'y': 50}},
            {'data': {'id': 'two', 'label': 'Node 2'}, 'position': {'x': 200, 'y': 200}},
            {'data': {'source': 'one', 'target': 'two','label': 'Node 1 to 2'}}
        ],
        layout={'name': 'preset'}
    )
])

if __name__ == '__main__':
    app.run_server(debug=True)

basic-usage

External layouts

You can also add external layouts. Use the cyto.load_extra_layouts() function to get started:

import dash
import dash_cytoscape as cyto
import dash_html_components as html

cyto.load_extra_layouts()

app = dash.Dash(__name__)
app.layout = html.Div([
    cyto.Cytoscape(...)
])

Calling cyto.load_extra_layouts() also enables generating SVG images.

Getting Started in R

Prerequisites

install.packages(c("devtools", "dash"))

Usage

Install the library using devtools:

devtools::install_github("plotly/dash-cytoscape")

Create the following example inside an app.R file:

library(dash)
library(dashHtmlComponents)
library(dashCytoscape)

app <- Dash$new()

app$layout(
  htmlDiv(
    list(
      cytoCytoscape(
        id = 'cytoscape-two-nodes',
        layout = list('name' = 'preset'),
        style = list('width' = '100%', 'height' = '400px'),
        elements = list(
          list('data' = list('id' = 'one', 'label' = 'Node 1'), 'position' = list('x' = 75, 'y' = 75)),
          list('data' = list('id' = 'two', 'label' = 'Node 2'), 'position' = list('x' = 200, 'y' = 200)),
          list('data' = list('source' = 'one', 'target' = 'two'))
        )
      )
    )
  )
)

app$run_server()

Acknowledgments

Huge thanks to the Cytoscape Consortium and the Cytoscape.js team for their contribution in making such a complete API for creating interactive networks. This library would not have been possible without their massive work!

The Pull Request and Issue Templates were inspired from the scikit-learn project.
