A bin&#x27;s start and end values are given in the value type of the metric it represents. For example, &quot;first contentful paint&quot; is measured in milliseconds and exposed as ints, therefore its metric bins will use int32s for its start and end types. However, &quot;cumulative layout shift&quot; is measured in unitless decimals and is exposed as a decimal encoded as a string, therefore its metric bins will use strings for its value type.
             &quot;density&quot;: 3.14, # The proportion of users that experienced this bin&#x27;s value for the given metric.
