## How it works

The core chart_builder interface for the ChartJS library that allows you to create a nice visual presentation of your data.

## Source files

* `lib/amd/src/chart_builder.js`
* `lib/amd/src/chart_*.js`
* `lib/templates/chart.mustache`

## Core api

Create a new instance of your required chart type

{{< php >}}
  $chart1 = new chart_bar();
  $series1 = new chart_series('Data type', $data);
  $chart1->add_series($series1);
  $OUTPUT->render($chart1);
{{< / php >}}


### JavaScript
