Re-think color scaling and bins #156

Open wklumpen opened 1 year ago

wklumpen commented 1 year ago

Currently, for cumulative measures we use a Jenks natural breaks method that considers the entire dataset to find breaks. This has a few issues:

It's data-intensive, and requires re-calculation when new data is introduced.
It might lead to clusters and bins which aren't all that useful (i.e. clustering by dates, which isn't useful). See #155 as an example.

We can use this space (or an issue in a future repository) to decide on a better approach going forward.
