# 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 [coreseekdev/react-org-chart](https://github.com/coreseekdev/react-org-chart). On top of it, we added a few customization to fulfill our requirements.
