Displaying graticule associated with JSON path [svg]

Community Help

Hi,
I want to display graticule on this map : https://observablehq.com/@jbaba/antarctica_ice_flow

I don’t understand why the graticule is not displayed. It seems to be related to the way I declare the svg. But, after many tries, there is still something I don’t understand.

Does anyone have a suggestion for me?
thanks in advance.

The difficulty here is that the graticule generated by d3.geoGraticule is in spherical coordinates, when the projection is expecting a metric crs, that matches the geospatial data.

Thanks Fil,
I see the point. It may take too long for me to find an alternative. I’ll move forwad.
