Cute Chess is currently using QCustomPlot for charts in the GUI. At the time of the implementation, Qt Charts was not available for open-source projects. Qt Charts has since been released under a compatible open-source license so it could be incorporated to Cute Chess.

The idea is to create a prototype of Cute Chess that uses Qt Charts instead of QCustomPlot. This would reduce the the amount of third-party code in our code base. For Qt Charts, we're also interested in the performance: drawing / plotting charts should not introduce unnecessary delay for the GUI.
