Looking for savable graphing methods

Chartist.js

If you are sending the data to a website, or serving the website yourself, using JSON as the data format will be the easiest. Personally I never use cloud services and I just use a Javascript charting library like https://gionkunz.github.io/chartist-js/ (it supports real-time graphs) on a web page that is self-hosted (run a server on the ESP32).

MIT App Inventor

First thought, play with MIT App Inventor https://appinventor.mit.edu/, they have dedicated blocks for graphing and cross-platform implementations of Bluetooth for Android and iOS. The data format is still up to you.
