from repo/bytes, sorted

from file-name suffix families discovered by a boundary radix tree · repo/bytes rank (thread height) · repo/commits-touching rank (thread brightness) · directory (colour)

from co-change degree

from repo/commits-touching rank (latitude) · directory (region) · repo/bytes density (terrain) · co-change links (chords)

from co-change communities found by modularity (clusters) · cluster-to-cluster coupling (placement) · partners inside the cluster (depth) · repo/bytes (node size) · repo/commits-touching (node brightness) · directory (node colour)

from src vs supporting code · directories · co-change links · repo/commits-touching

from directories · co-change coupling · repo/bytes · repo/commits-touching

from directory-ordered files · repo/bytes · repo/commits-touching · co-change links

from co-change shortest path from a chosen file (shell radius) · directory (sector and colour) · repo/bytes rank (node size)

from co-change rolled up to directory pairs (roads) · repo/commits-touching rank (speed) · repo/bytes rank (vehicle length) · directory (colour)

from co-change pairs of 3+ commits (bonds) · commits per pair (multiplicity and bond length) · repo/bytes rank (atom size) · directory (colour)

from repo/bytes rank minus repo/commits-touching rank (depth) · repo/bytes rank (size) · repo/commits-touching rank (light) · directory (column and colour)

from co-change betweenness (removal order) · largest connected piece under removal (the shoreline) · co-change degree (the control) · directory (colour)

from co-change pairs filtered by how many commits they repeat in · degree assortativity · clustering · same-directory share, each recomputed per threshold

from sum of repo/commits-touching and sum of shared commits over pairs, bounded against the commit count — the envelope of every commit-breadth distribution the evidence permits

from shared commits over repo/commits-touching — the conditional probability a partner also changed, in one direction · commits as evidence weight · directory (colour)

from the same files ranked five ways in turn — repo/bytes · repo/commits-touching · co-change degree · repo/commits-touching ÷ repo/bytes · path — with Spearman between each consecutive pair, and total travel per file · directory (colour)

from Horizon's envelope revolved around the rank axis — commit rank (radius) · the files a rank is proven to have touched (the bright disc) · the widest the evidence permits it (the corona) · the first rank whose lower bound is zero (the dark centre)

from repo/commits-touching as swings per cycle (rate) and as rank (position along the row) · repo/bytes rank (bob size) · directory (colour) — the row recombines because every count is a whole number

from for every source file, the test that has shared the most commits with it — shared commits over repo/commits-touching — and whether a test shares its name · directory (colour)

from repo/bytes and repo/commits-touching, each sorted ascending and summed — the Lorenz curve and Gini of both, and the share held by the top 10%, 20% and 50% of files

from connected components of the co-change graph (islands) · file count (area) · directory (colour) · the longest directory prefix an island's sources share (name)

from for each directory, couplings with both ends inside it over couplings with at least one end inside — cohesion(), ranked · files placed and refused per directory

from the fewest shared-commit steps between every pair of files, as a histogram · the pairs no chain joins, counted · the median and the diameter

from articulation points of the co-change graph, by depth-first low-links · for each, the files cut off from the largest piece without it, by a second exact search · directory (colour)

from k-core decomposition of the co-change graph — every file's coreness, by repeated peeling · the deepest shell checked pair by pair for completeness · directory (colour)

from for each test file, the source directories it has shared a commit with, and shared commits summed per directory · tests recognised by name and by top-level test directory

from repo/commits-touching (up, log) · distinct co-change partners (across, log) · the median of each as the cut · a count of files in each of the four quadrants · directory (colour)

from rank by distinct co-change partners against rank by betweenness — Keystone's betweennessOf, per file · the largest gaps between the two ranks, named · directory (colour)

from k-core decomposition of the co-change graph — every file's coreness, by repeated peeling — as shells flying out from one point to the radius their rank earns · the deepest shell checked pair by pair for completeness · repo/bytes rank (mote size) · directory (colour)

from history — every listed commit's author, moment and placed files — replayed on a clock · Containment's treemap as the ground (repo/bytes footprint) · repo/commits-touching rank (height) · directory (colour)
