Circle plot for Lightning

Documentation and examples at lightning-viz.org

The Lightning server provides API-based access to reproducible, web-based visualizations. It can be deployed in many ways, including Heroku, Docker, a public server, a local app for OS X — and even a server-less version well-suited to notebooks like Jupyter. It comes bundled with a core set of visualizations, but is built to support custom ones.

You can create an adjacency visualization using Python, Scala, JavaScript, or R by using API clients for making requests to a Lightning server.

Take a look at each client for installation and usage examples:

• Python
• Scala
• JavaScript
• R

from lightning import Lightning
from numpy import random

lgn = Lightning()

connections = random.rand(50,50)
connections[connections<0.98] = 0

g1 = (random.rand(50) * 3).astype('int')
g2 = (random.rand(50) * 3).astype('int')
group = [g2, g1]

lgn.circle(connections, group=group)

import org.viz.lightning._
import scala.util.Random

val lgn = Lightning()

val connections = Array.fill(50)(Array.fill(50)(Random.nextDouble()).map{ d =>
	if (d < 0.98) {
		d
	} else {
		0.0
	}
})

val g1 = Array.fill(50)(Random.nextInt() * 3)
val g2 = Array.fill(50)(Random.nextInt() * 3)
val group = g1 + g2

lgn.circle(connections, group=group)

lightning-circle is an npm module that can be used on its own.

npm i --save lightning-circle

var Circle = require("lightning-circle")

var el = document.createElement("div");
document.body.appendChild(el);

var data = {
  nodes: [0, 1, 2, 3, 4, 5, 6, 7, 8],
  links: [[0, 1], [0, 2], [3, 5], [2, 4], [1, 2], [3, 4], [1, 5], [1, 6], [2, 7], [2, 8], [3, 8], [8, 7]],
  labels: ["a", "b", "c", "d", "e", "f", "g", "h", "i"],
  group: [[0, 0, 0, 1, 1, 1, 2, 2, 2]]
};

var options = {
  labels: true,
  width: 600,
  height: 400
};

var circle = new Circle(el, data, options);

Arguments:

• selector – css selector or dom node that will act as parent node of the visualization
• data – the required data for the Visualization
  • nodes – array representing nodes in the visualization
  • group – array representing groups
  • links – array of arrays describing the links between nodes
  • labels – array of strings
• options
  • width – Number – the width of the visualization
  • height – Number – the height of the visualization
