ESP32: Plot graphs through a webserver/webportal (WiFi Part 4) - Arduino

This video shows how to plot graphs / charts in real-time with the ESP32 webserver/webportal. This will allow you for instance to plot sensor values over time when using the ESP32 as IoT gateway.

This video expands on the webserver code explained in part 3:
