Map of Ireland, with North-South boundary delimited.
SVG should be fairly easy to alter or expand. For example the following can all be achieved with one-line CSS changes:

• You can toggle the Northern Ireland border on/off or change its thickness
• You can change any of the colours
• You can draw a border around all the land to make it more distinct from the sea
• You can hide Northern Ireland or the Republic of Ireland.

You can also do any of the following just by changing or adding/removing a few lines of SVG code:

• Zoom in on Northern Ireland, the Munster shoreline, or any other area
• Remove all the small islands (e.g. for faster rendering)
• Add drop shadows (feGaussianBlur), textured ground (feTurbulance) or topography (feDisplacementMap + feSpecularLighting)
• Add cities and towns.
• Add rivers. Anyone care to do this?
