I open sourced the project because I wanted to avoid a repeat of the Google Image Charts scenario, in which people are dependent on proprietary image chart solutions that can be shut down at any time. Also of note, you can use the QuickChart-Zapier integration to create Zapier charts.
Head to QuickChart.io to try it out. Enjoy!
