first example endpoint. it's a 25x21 rectangle (the size is provided in the 'style' arg to the Endpoint), and it's both a source

'exampleConnection' and can only be dropped on an Endpoint target that declares 'exampleEndpoint' as its drop scope, and also that
only 'exampleConnection' types can be dropped here.
the connection style for this endpoint is a Bezier curve (we didn't provide one, so we use the default), with a lineWidth of
5 pixels, and a gradient.
