# d3-state-visualizer
|
||
|
||
Enables real-time visualization of your application state.
|
||
|
||
Created by [@romseguy](https://github.com/romseguy) and merged from [`reduxjs/d3-state-visualizer`](https://github.com/reduxjs/d3-state-visualizer).
|
||
|
||
[Demo](http://reduxjs.github.io/d3-state-visualizer)
|
||
|
||
## Installation
|
||
|
||
`yarn install d3-state-visualizer`
|
||
|
||
## Usage
|
||
|
||
```javascript
|
||
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](https://github.com/reduxjs/redux-devtools/tree/master/packages/map2tree) or [react2tree](https://github.com/romseguy/react2tree)
|
||
- `state`: a plain javascript object mapping arbitrarily nested keys to values – which will be transformed into a tree structure, again using [map2tree](https://github.com/reduxjs/redux-devtools/tree/master/packages/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](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox) in order to preserve the aspect ratio of the chart. [Great video](https://www.youtube.com/watch?v=FCOeMy7HrBc) 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](https://github.com/reduxjs/redux-devtools/tree/master/packages/d3tooltip) | Sets the options for the [tooltip](https://github.com/reduxjs/redux-devtools/tree/master/packages/d3tooltip) 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...

## Bindings
|
||
|
||
### React
|
||
|
||
[example](https://github.com/reduxjs/redux-devtools/tree/master/packages/d3-state-visualizer/examples/react-tree) implementation.
|
||
|
||
## 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.
