Scaling, scrolling, and panning.
UI explained:
	- Use Scale X and Scale Y to zoom in the chart. You can scale the chart anisotropically.
- Use Offset X and Offset Y to move the origin of the chart.
- You cannot move the chart outside its boundaries.
		
			- Example: if both scale factors are 1, you cannot move the origin — you should zoom in first.
 
- After applying scale/offset to the chart, sliders' positions change to reflect actual values.
- When you zoomed in, you can grab chart with mouse and move around (pan).
		
			- Warning: can be slow on some browsers.
