Invert Y-axis in line charts

Hello Metabase Team,

Would it be possible to add an option to **invert the Y-axis in line charts**?

I suspect this request may already have been raised before, and I have seen a few workarounds involving negative values. However, having this as a native feature (ideally available as a toggle in the chart settings) would be especially useful.

This would be especially useful for **SEO visibility reporting** and other cases where lower values are more important to emphasize.

Thanks in advance, and apologies if this is a duplicate request.

The issue names no files, tests, or entry points. Start by locating the line-chart settings and rendering entry points, then determine how a Y-axis inversion option would fit; done means the option is available for line charts and the resulting axis is visibly inverted.
