title: Is it possible to draw charts on an ESP8266 web server that runs as an access point?
body: <p>My ESP8266, configured as an access point, is currently programmed to read multiple DS18B20 sensors and store read values in a text file on an SD card. I can connect to the AP from my Android phone and navigate to 10.10.10.1 (the ESP's static IP address) in  the browser, where I can change settings (read interval time/delete SD card data) through HTML/JS and view stored values which are presented in an HTML table.</p>
  
  <p>I was wondering if there's a way to draw a simple 2D chart with multiple lines (each sensor its line) without any need to connect to the web to obtain libraries like Google charts, which is not an option, because the controller is meant to be placed in remote places without signal. The ESP's purpose is to obtain data over time, which can later be presented to the user over a web server.</p>
