Can we add a relationship diagram between roles？

Can you add a feature to build relationships between characters, represented in the form of charts, to facilitate inspiration for creators, and can also be used on some combined items. I really hope to have this feature, it's really necessary.

This may be a useful feature. You can already cross-link characters, but there is no chart.

Please make a feature request under "Issues".
