Usage is proportional to the number of marker updates. Every time you update map markers, some computation is required to calculate the optimal position
of the markers. The compute is provided by an API endpoint which is used by the library internally.
Usage pricing is scales per million marker updates per month.
Usage does not increase on cache hits. For example if you use the same markers on your map multiple times, subsequent compute requests will hit the
cache and the usage is not increased. The cache is invalidated after a certain time.
