@naegelyd I removed `initialize` from core. B/c it's not being called, the height/width of the chart is messed up. Placing the code inside the constructor solves this issue.
Nit, indent this line so it becomes:

```javascript
this.$el.append('<option value="' + model.id + '">' +
                model.get('name') + '</option>');
```
