New matrix visiualisation in preview

I don't normally include preview features for this blog series, but the new matrix is too important not to mention:

The above setting would give a new matrix like this:

The regions are indented in by 10 (whatever the unit is!).

Perhaps best of all, you will be able to click on a single figure to see the effect on other visualisations:
