Description

As the title says, when zoomed in and the chart resizes, the zoom is reset. Could be useful to keep track of the state, and then zoom programmatically when the chart is drawn.
This is similar to issue #252

Here is an example of how to do it:

Research direction

Start by tracing how the chart handles resizing and redraws, then compare the behavior with issue #252 and the linked D3 zoom-to-domain example. Done means a zoomed chart keeps its zoomed domain after resizing instead of resetting.
