Coverage Graph
The subjects BvLogic publishes and the links that genuinely exist between them, generated from the built site. Includes what we cover and never connect to anything, which is the useful half.
183 subjects, 570 links between them, generated from the built site on 2026-08-11.
An edge means one of our pages links to another. It does not mean the two subjects are related in the world, and the absence of an edge means we have not written the connection, not that none exists.
How it is built
Nodes are the subjects we publish. Edges are internal links that genuinely exist in the body of a page, with navigation, breadcrumbs and the footer excluded. Those link every page to every other page, and a graph in which everything connects to everything is the same as no graph at all. A connection that was intended and never written does not appear here, which is the point: the graph reports what we did, not what we meant to do.

What we cover and never connect to anything
None. Every live subject now connects to at least one other. It was 24 when this graph was first generated, including every tool and every product page, and that measurement is what prompted the fix rather than the other way round. A further 17 isolated subjects sit in planned or partial sections, where sparseness is expected and is not counted as a gap.
Reciprocity
52.1% of links between live subjects are reciprocal; 273 are one-way. A one-way link is often correct - a detailed page citing a broad one does not oblige the broad one to point back at every page that cites it - so this is a number to understand rather than to drive to a hundred.
It is measured here because its absence hid a real defect. A related-subjects block was added to one set of pages and, through a second code path, silently not rendered on the pages it pointed at. Isolation fell from 24 to 1 and looked like a complete fix, because an edge counted from either end. Connectivity and reciprocity are different properties, and reporting only the first made a half-finished change look finished.
What this does not tell you
Nothing about importance. A densely connected subject is one we have written about a lot, which reflects our attention rather than the market's. Nothing about correctness either: the graph counts links, and a link to a weak page counts the same as a link to a good one. It is a map of shape, and shape is only one of the things worth knowing about a body of work.
