I'm new to Sencha Architect and I'm trying to figure out how to use the Draw library in Architect. I have tried to create a draw component and add it to a container but it does not seem to work.

Here is the code I added to the add event of the parent container:
var drawComponent = Ext.create('Ext.draw.Component', {
viewBox: false,
items: [{
type: 'circle',
fill: '#79BB3F',
radius: 100,
x: 100,
y: 100
}), surface = drawComponent.surface;
