You may pass either a number or an object to the zoom property on a <hex-map>. When passing an object, keys are breakpoints and values are the zoom level.

For example, if your breakpoints are 600, 900, 1200, and 1800; you might do something like:

<hex-map
  access-token = "pk.eyJ1IjoiY3VydGlzYmxhY2t3ZWxsIiwiYSI6ImNpdXlibnY1eTA0bW4yb24wNjh5Y2pkOWsifQ.4EEQwMrBd06fiFZshvfcug"
  style        = "mapbox://styles/curtisblackwell/ciuy9b96k00gb2js5em4uhnoa"
  ref          = "map"
  :zoom        = "{
      0:  10,
     600: 12,
    1200: 13,
  }"
>
  ...
</hex-map>

Setting a zoom value for a breakpoint of 0 ensures a desirable zoom level for the smallest of screens.
