sflow -> aggregated aspath visualization?

You could use Prometheus / Grafana to build the dashboards.

The following example is a starting point (top ASNs / Countries by traffic

The example could be modified to make the make router / interface
selectable, or cloned to create separate per router / interface dashboards.
