Messing around with programmatic graphics to display on a 1.8" TFT display connected to my Pi Cluster. The is not a whole lot of pixel real estate to display much, but I think I've got the basics down.

Pink - current CPU temperature
Orange - CPU utilization graph (span is about 30 minutes)
Blue - Memory utilization graph (span is about 30 minutes)

Each node runs a python script from a cronjob. The master node uses ansible to fetch all the data JSON files.
