## Creating a Chart
|
|
|
|
It's easy to get started with Chart.js. All that's required is the script included in your page along with a single `<canvas>` node to render the chart.
|
|
|
|
In this example, we create a bar chart for a single dataset and render that in our page. You can see all the ways to use Chart.js in the [usage documentation](./getting-started/usage.md).
|
|
```html
|
|
<canvas id="myChart" width="400" height="400"></canvas>
|
|
<script>
|
|
var ctx = document.getElementById("myChart").getContext('2d');
|
|
var myChart = new Chart(ctx, {
|
|
type: 'bar',
