The first "final" chart pans and zooms wrong. It appears that it pans roughly half the distance that I move the mouse and scrolling to zoom zooms on a point that isn't the mouse.

However the d3fc-zoom chart near the bottom works perfectly.

these all worked for me; I didn't understand the difference between the native version and the new component.

Thanks for the feedback. Depending upon the devicePixelRatio, interactions with the first chart would misbehave. I've just pushed a fix to the code, and updated the post, which should rattle through the various CDNs before too long.
