I am trying to create a mark for use with Plot that displayed curved text along a path. This should be possible as SVG supports this natively. However, it would appear that text placement along a path is browser dependent. While I would expect there to be some minor differences in text-metrics across browsers, there appears to be a more significant problem with text anchoring and offset.
This results in expected behaviour in Safari (e.g. centred text in the example below), but not in Chrome (offset too far to the right). When setting the anchor to start or end placement is quite different across browsers so not really useable.
