[postgis-users] SVG Render Issue

I am outputting EPSG 4326 (WGS84) polygon data as svg from postgis. I  
am however struggling to get anything to render as SVG. Does anyone  
know the correct viewBox and path transform setup to allow this type  
of data to render as svg. Or should I be using a different method?

Here is an example of what I am currently doing. The path should  
render a low res polygon of Oxford, UK.

Thanks for your help,

Toby
