👋 I believe it would be useful to cluster the locations in order to quickly find out what points belong to what criticalmass. This would then enable other functionaly: like estimating the direction of each critical mass.

The API could just have another field per record with a cluster number.

Depending on the method the clusters could be computed on the fly or on a regular basis in the background.

I would be happy to work on something. Depending on the algorithm there could either be a pure JS algorithm or there is another local http service giving the cluster estimates.

Questions:

• do you think this is useful?
• would you accept a pull request?
• are there open datasets of past critical masses?
