I am just writing an small full stack example with Precept and Datomic. https://github.com/ThinhPTran/preceptdirectional

Nice!

Looks good! How’s it going so far?

It is working now. You need to login first, then you can change table value (deviation)

there are two tables and charts

one for user's local change

one for all users' changes

and a slider to go back to the history

look better than reagent alone!!!
