The citation map
Ten of the most-cited decisions in this library, and every case in it that cites them. One panel per decision, because ten colours on one chart is a rainbow and a rainbow answers nothing.
Measured 19 August 2026 · 225 citing decisions
The centre is the decision. Every dot around it is a decision in this library that cites it — all of them handed down this year. The shade is the age of the authority at the centre, which is the thing worth seeing: a 1991 case ringed by 2026 citations is a rule still doing work.
A line here means one decision cited another on a date. It does not mean the case was followed, distinguished, limited or overruled — that judgment is made by editors at West and Lexis and sold, and a map that pretended to it would be guessing in a way you could not check.
And it is drawn from the citations traced so far, not from every citation that exists. A thin panel means this library has traced few links to that decision, which is a fact about the map and not about the case.
The same graph is what the citation checker walks when it asks whether the authority the other side is leaning on has been touched since they wrote it.
