+    QChart is a QGraphicsWidget that you can show in a QGraphicsScene. It manages the graphical
+    representation of different types of QChartSeries and other chart related objects like
+    QChartAxis and QChartLegend. If you simply want to show a chart in a layout, you can use the
+    convenience class QChartView instead of QChart.
