A small graph built on Chart.js to view ArduinoAQI and PurpleAir sensor data. To retrieve ThingSpeak API keys and sensor IDs from publicly accessible PurpleAir sensors, inspect data from the PurpleAir API.

The graph uses the following GET variables:

• sensors - A comma-delimited collection of ThingSpeak sensor IDs and read API keys, e.g. sensors=123|asdf,345|qwer
• results (optional) - Number of results, defaults to 100
