Using SVG to display the Management Structure of an NHS Trust
The first link calls a HTML file which encapsulates a pretty much blank SVG which calls two scripts: the first calls the MSXML parser to read the OWL and give it the data it needs to create the picture; the second was developed by Peter Sorotokin at Adobe and allows for scrollbars to be used in the SVG image.
The second link calls a near identical copy of the SVG file previously used and then uses the XML parsing abilities of the Adobe plug-in to read the data from the OWL in order to draw the picture. Because we're not using MSXML we don't need to encapsulate the image in an HTML document but we could do if we so desired.
All images time themselves in microseconds in order to give an idea about how quick each approach is. Generally (and please email me if this isn't the case for you), the method without MSXML is quicker. This approach should mean that it is also more accessible to users of other browsers, but this has yet to be tested.
To navigate within an SVG document:
While researching other solutions I came across Microsoft's Visio and from this csv file produced this. I also produced this SVG which stitches all the elements together in one diagram. This contrasts with my first attempt carried out in freehand using CorelDRAW 11.
