> optimized for React or Vue

It means you can invoke `renderChart()` as many times as you wish.

E.g. in `React`:
```
import React, { Component } from 'react'
import { renderChart, destroyChart } from '...'

class Chart extends Component {
  ...
  render () {
    return <div ref={(el) => this.$wrapper = el}/>
  }
  
  componentDidUpdate () {
    renderChart(this.$wrapper, this.props.data)
  }
  
  componentWillUnmount () {
    destroyChart(this.$wrapper)
  }
  ...
}
```
E.g. in `Vue`:
```
<template>
  <div ref="$wrapper"></div>
</template>

<script>
import { renderChart, destroyChart } from '...'

export default {
  name: 'chart',
  ...
  watch: {
    data () {
      renderChart(this.$refs.$wrapper, this.data)
    }
  },
  beforeDestroy () {
    destroyChart(this.$refs.$wrapper)
  }
  ...
}
</script>
```
