It should just use strings as labels (just like what happens when x= ['a','b','c','d'] ).
A simple work around is to prefix the strings with &nbsp; to sabotage the convertion.

You can set layout.xaxis.type = 'category' to keep the strings.

You can also set layout.autotypenumbers = 'strict' (which is currently in the default plotly.py template, but in plain plotly.js the default is 'convert types') https://plotly.com/javascript/reference/layout/#layout-autotypenumbers
