d3-state-visualizer

This package was merged into the redux-devtools monorepo. Please refer to that repository for the latest updates, issues and pull requests.

Enables real-time visualization of your application state.

Demo

Installation

npm install d3-state-visualizer

Usage

import { tree } from 'd3-state-visualizer';

const appState = {
  todoStore: {
    todos: [
      { title: 'd3'},
      { title: 'state' },
      { title: 'visualizer' },
      { title: 'tree' }
    ],
    completedCount: 1
  }
};

const render = tree(document.getElementById('root'), {
  state: appState,
  id: 'treeExample',
  size: 1000,
  aspectRatio: 0.5,
  isSorted: false,
  widthBetweenNodesCoeff: 1.5,
  heightBetweenNodesCoeff: 2,
  style: {border: '1px solid black'},
  tooltipOptions: {offset: {left: 30, top: 10}, indentationSize: 2}
});

render();

Charts API

The APIs are minimal and consists of a single function you provide with:

• a DOM element
• a plain old JS object for options.

Tree

This chart is a bit special as it accepts either one of the two following options, but not both:

• tree: a properly formed tree structure such as one generated by map2tree or react2tree
• state: a plain javascript object mapping arbitrarily nested keys to values – which will be transformed into a tree structure, again using map2tree.

Other options are listed below and have reasonable default values if you want to omit them:

Option	Type	Default	Description
id	String	'd3svg'	Sets the identifier of the SVG element —i.e your chart— that will be added to the DOM element you passed as first argument
style	Object	{}	Sets the CSS style of the chart
size	Number	500	Sets size of the chart in pixels
aspectRatio	Float	1.0	Sets the chart height to size * aspectRatio and viewBox in order to preserve the aspect ratio of the chart. Great video if you want to learn more about how SVG works
widthBetweenNodesCoeff	Float	1.0	Alters the horizontal space between each node
heightBetweenNodesCoeff	Float	1.0	Alters the vertical space between each node
isSorted	Boolean	false	Sorts the chart in alphabetical order
transitionDuration	Number	750	Sets the duration of all the transitions used by the chart
tooltipOptions	Object	here	Sets the options for the tooltip that is showing up when you're hovering the nodes
rootKeyName	String	'state'	Sets the first node's name of the resulting tree structure. Warning: only works if you provide a state option
pushMethod	String	'push'	Sets the method that shall be used to add array children to the tree. Warning: only works if you provide a state option

More to come...

Roadmap

• Threshold for large arrays so only a single node is displayed instead of all the children. That single node would be exclude from searching until selected.
