Round edges of line chart with step interpolation

[bjornevik]

Hi!

I need a line chart with rounded edges and step interpolation, à la:

According to the docs I see that

You can also provide a function if you need to adjust parameters for d3-shape curves or to use a custom curve function.

The link in the documentation doesn't seem to exist anymore, but I did find this page https://d3js.org/d3-shape/curve from it.

Is there a way to do this without messing around with custom interpolation? If not, any examples of using custom interpolation is appreciated.
