    1. COI dont know of any quick solution to this, but I would either: position the circles vertically and horizontally centered in a wrapper with more height&width and then make them bigger inside the wrapper (still being centered). OR you can place them via js-calculation according to the animation state with dynamic offsets.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
