# React Organizational Chart
[![npm version](https://badge.fury.io/js/%40unicef%2Freact-org-chart.svg)](https://badge.fury.io/js/%40unicef%2Freact-org-chart)

React component for displaying organizational charts.

This component is based on [unicef/react-org-chart](https://github.com/unicef/react-org-chart).

# Features

From the previous package:

- High-performance D3-based SVG rendering
- Lazy-load children with a custom function
- Handle up to 1 million collapsed nodes and 5,000 expanded nodes
- Pan (drag and drop)
- Zoom in zoom out (with mouse wheel/scroll)
- Lazy-load of parents (go up in the tree)
- Zoom in, zoom out and zoom buttons.
- Download org chart as image or PDF

What we added:

- Renamed `person` to `entity` throughout the codebase
- Removed `department`
- Added `subTitle` text element under the `title`.
- Added config props functions to get all the text values (`getName`, `getTitle`, `getSubTitle`, `getCount`)
- Added config props for all text values on click events (`onNameClick`, `onTitleClick`, `onSubTitleClick`, `onCountClick`)
- Added config props for the font sizes (`nameFontSize`, `titleFontSize`, `subTitleFontSize`, `countFontSize`)
- Added config props for the text truncation (`nameTruncateLength`, `titleTruncateLength`, `subTitleTruncateLength`)
- Added tooltips to all text values since we now support truncation

    <OrgChart
      tree={tree}
      downloadImageId="download-image"

        // Setting latest config to state
        this.setState({ config: config })
      }}
      loadConfig={d => {
         // Called from d3 to get latest version of the config.
        const config = this.handleLoadConfig(d)
        return config
      }}
      loadParent={personData => {
        // getParentData(): To get the parent data from API
        const loadedParent = this.getParentData(personData)
        return Promise.resolve(loadedParent)
      }}
      loadChildren={personData => {
        // getChildrenData(): To get the children data from API
        const loadedChildren = this.getChildrenData(personData)
        return Promise.resolve(loadedChildren)
      }}
      loadImage={personData => {
        // getImage(): To get the image from API
        const image = getImage(personData.email)
        return Promise.resolve(image)
      }}
      // getTitle / getSubTitle / getCount work the same way & with the same args
      getName={(data, truncate, truncateLength) => `The great ${data.person.name}${truncate}`}
      // onTitleClick / onSubTitleClick / onCountClick work the same way  & with the same arg
      onNameClick={data => console.log(data.person.name)}
