Rotated Axis Labels

This example demonstrates how to rotate axis labels by 90° using post-selection. After the axis is rendered, the text label elements are selected, and then attributes on the elements are modified to customize the label appearance.

simpler & robust with regards to text sizing:

  .selectAll("text")
    .style("text-anchor", "start")
    .style("writing-mode", "vertical-rl");

alternatively, to achieve rotate(-90):

  .selectAll("text")
    .style("text-anchor", "start")
    .style("writing-mode", "sideways-lr");

but sideways-* is supported by Firefox only ... a work-around for all browsers:

  .selectAll("text")
    .style("text-anchor", "end")
    .style("writing-mode", "vertical-rl")
    .style("transform", `rotate(180deg)`);

again needs some tuning of the final position ...
