Hello,

I wanted to report that a small logic error stops SSR from working for XYchart.

In useScales line 43, x/yScale will be returned as undefined if there are no values in the dataRegistry. This stops render of all children of XYChart (Axis, Grid, etc.).

In withRegisteredData line 56, the Series component will not be rendered if there is no x/yScale. This is done on line 48 in a useEffect block. I would propose moving the initial registerData call out of useEffect.
