I would like to be able to show a popup window with the chart like I do in Python.

I pasted the data class example into my spring boot application and when I run I get:

Caused by: java.awt.HeadlessException: null

If I comment the .show() and call .save() I get:

java.lang.IllegalArgumentException: No enum constant kravis.render.PlotFormat.

Please tell me if I'm missing something.

Thanks, Michael

To solve the headless exception, I used:

-Djava.awt.headless=false
