not able to add custom attributes to the axis

[shivasai09]

we now that using axisBottom or axisRight or any other axis making function, we get the below HTML,

but my concern is how to add custom attributes to the <line> or <text> elements.

I need this to increase the accessibility for our product. if it is possible to add custom attributes to <line> or <text>, then i would like to add the aria-* attributes to it so, that my screen reader will be able to give more descriptive information.

can any one help me how to achieve this.?

Thanks,
Siva

You can call a function after applying an axis, see https://observablehq.com/@d3/connected-scatterplot#xAxis for an example.
