 ## Drawing architecture
 We have a *_chart_painter.dart class per each chart type. It draws elements into the Canvas.
-Because we wanted to test draw functions we made the CanvasWrapper class.

-You should use it in your draw functions, Instead of direct accessing to canvas.
-It makes writing tests for draw functions possible.
