an exmple of how I used to host charts for my personal finances. I've abandoned it now, because I haven't really looked at charts, but it was fun to setup.
powered by:
nice things about the setup:
- it's completely within free tiers (as of December 2022)
- no vendor lock - host your grafana and prometheus as you wish
- prometheus image has all the data backed on the build step, so it's read only
it's based on Michael Walker's setup.
