Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
This is an authored directed relation from the source endpoint to the target endpoint.

Authored annotation
induce metric uniformity
Authored explanation
The entourages d(x,y)<ε define the canonical uniformity of a metric space.
How to interpret this relation type
Pass canonically from a stronger object to structure it determines, or forget part of the data while retaining a valid weaker structure. The carrier may change under a canonical induced construction.

+ uniformity
Authored explanation
Choose entourages satisfying the uniformity axioms.
How to interpret this relation type
Equip an existing carrier or structured object with additional chosen data, when such compatible data exists. Use a construction junction when several independently meaningful inputs must coexist on the same carrier or interact compatibly.

induce topology
Authored explanation
Every uniformity canonically determines a topology by its entourages.
How to interpret this relation type
Pass canonically from a stronger object to structure it determines, or forget part of the data while retaining a valid weaker structure. The carrier may change under a canonical induced construction.
