When: use to see a diagram before you edit it and after each round of changes; this is how you check your work. It answers in milliseconds from the saved diagram, where export_diagram starts a browser for 6-10 s. Returns a text map: the zones as a tree, each with its place on a coarse grid (r1 = top row, c1 = left column) and its nodes (label, type, icon, #id), then the edges, then the checks a render would reveal: overlapping nodes, overlapping sibling zones, nodes sticking out of their zone, nodes not laid out yet, empty zones, and the validator's error and warning counts. Every #id works as a node reference in the canvas_* tools. It also says when an edit_diagram run or a generation is still in progress on the diagram, and gives a preview image link that renders only if opened. For a large diagram, pass zone to look at one zone. include_image also renders a PNG (slow: only when you need to see styling). Next: fix what the checks report with the targeted canvas_* tool, then canvas_view again.
