Zovo Swimlane

Use this when the user wants a process with lanes checked without a drawing, for example "check my process for steps that do not reach the end" or "which steps are unreachable". Takes the same lanes, steps and links as make_swimlane. Returns unknown lanes and step ids, duplicate ids, steps not reachable from a start step, steps with no path to an end step, decisions with fewer than 2 outgoing links or unlabeled branches, end steps with outgoing links, and loops (allowed, listed). Draws nothing and makes no files. Up to 12 lanes, 150 steps, 300 links. Does not rewrite or fix the process; do not use it for plain flowcharts without lanes.

Use this when the user wants a swimlane diagram, cross-functional flowchart or process map with roles, teams or systems as lanes, for example "draw our order process as a swimlane" or "make a swimlane PDF of who does what". Takes lanes in order, steps (id, lane, text, kind: step, decision, start or end) and links (from, to, label; branches that leave a decision need labels), plus orientation (horizontal: lanes as rows, flow left to right; vertical: lanes as columns, flow top down), page size and title. Returns counts, each step's lane and flow position, unreachable steps, steps with no path to an end, loops, a geometry check (steps outside their lane, overlapping steps and labels, lines crossing a step), an interactive diagram, and PDF, SVG and CSV downloads. Refuses, with the reason: unknown lanes or step ids, duplicate lanes, ids or links, a link from a step to itself, a missing start or end step, an end step with outgoing links, decisions with fewer than 2 outgoing links or with unlabeled or repeated branch labels. When one step with its branch labels is wider than the page at 6 pt, it returns the SVG and CSV without a PDF and says why. Up to 12 lanes, 150 steps, 300 links. Does not draw plain flowcharts without lanes, BPMN message flows, org charts or sequence diagrams. Download links of large diagrams expire after about 1 hour.
