Interactive SVG graphic. 30 features are clickable. Cursor changes into a hand indicating item is "clickable". This will pop-up a photograph.
To zoom & pan please use the orange & white control in top left corner.
The "interactive" isn't perfect. So after a photo has popped-up please press "Ctrl" and "W" keys simultaneously to return to the diagram.
Tested it on Windows 7 using the latest Firefox, Safari, Chrome and IE11 browsers, (22-FEB-17).
