The use case is:
- A cpp data source being updated constantly;
- A 2D line graph drawing based on the data, where the x axis moves to show the new data received;
- The ability to scroll "back" and see previously added data.
With the provided code, we see the performance drastically decrease after ca. 1000 points added.
