- Edge widths grow logarithmically with the connection count (~1 px at
a single count, uncapped); connections below 1% of total traffic are
pruned, bounding the graph to ~100 edges.
- Beads: per-direction flows emitted at a rate linear in the count,
each bead simulated independently in JS (no in-flight limit), offset
onto right-hand lanes so opposing flows don't collide, running under
the node circles with a glow.
- External links: referer origins as a node row above the map, exit
origins fanned outwards from their source page.
- Transitions are now stored per 5-minute bucket (sparse
from -> to -> bucket -> count) so the graph filters by time range
like the other series; legacy analytics files are discarded.
