Ah,
The timeline is loaded from 'xml/timeline.xml'
It seemed reasonable to me that a relative path to the
icons should start at the path to the main html file,
datavis_demo.html, but the path
icons/green_circle.png
gets interpreted as
xml/icons/green_circle.png
Is this as it is supposed to be or is this a bug?
