What are vue-chartjs's main functionalities?

Line Chart

This code sample demonstrates how to create a simple line chart using vue-chartjs. The `Line` component from vue-chartjs is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <line-chart :chart-data="datacollection" :options="options"></line-chart>
</template>

<script>
import { Line } from 'vue-chartjs'

export default {
  components: {
    LineChart: Line
  },
  data () {
    return {
      datacollection: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 39, 10, 40, 39, 80, 40]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }
    }
  }
}
</script>
```

Bar Chart

This code sample demonstrates how to create a bar chart using vue-chartjs. The `Bar` component is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <bar-chart :chart-data="datacollection" :options="options"></bar-chart>
</template>

<script>
import { Bar } from 'vue-chartjs'

export default {
  components: {
    BarChart: Bar
  },
  data () {
    return {
      datacollection: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 39, 10, 40, 39, 80, 40]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }
    }
  }
}
</script>
```

Pie Chart

This code sample demonstrates how to create a pie chart using vue-chartjs. The `Pie` component is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <pie-chart :chart-data="datacollection" :options="options"></pie-chart>
</template>

<script>
import { Pie } from 'vue-chartjs'

export default {
  components: {
    PieChart: Pie
  },
  data () {
    return {
      datacollection: {
        labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: ['#FF6384', '#36A2EB', '#FFCE56', '#4BC0C0', '#9966FF', '#FF9F40'],
            data: [12, 19, 3, 5, 2, 3]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }

  BarElement,
  CategoryScale,
  LinearScale
} from 'chart.js'
import { Bar } from 'vue-chartjs'

ChartJS.register(CategoryScale, LinearScale, BarElement, Title, Tooltip, Legend)

export default {
  name: 'App',
  components: {
    Bar
  },
  data() {
    return {
