2. Link the ART library to your ReactNative project ([how to link a library](https://facebook.github.io/react-native/docs/linking-libraries-ios.html#content)). You'll find the React ART library in `node_modules/react-native/Libraries/ART/ART.xcodeproj`


## Usage

```jsx
// @flow
import * as React from "react";
import { ScrollView, Easing } from "react-native";

import Pie from "react-native-animated-pie";

export default class PieExample extends React.Component<any> {
  render() {
    const series = [40, 12, 68, 100, 25, 45, 200, 11];
    const delay = 0;
    return (
      <ScrollView>
        <Pie
          series={series.map(d => d).sort((a, b) => b - a)}
          height={380}
          outerRadius={100}
          easing={Easing.linear}
          delay={delay}
        />
        <Pie
          series={series.map(d => d).sort((a, b) => a - b)}
          outerRadius={100}
          height={200}
          innerRadius={55}
          delay={delay + 1000}
