`render_diagram`Use for any system design, architecture, data-flow or infrastructure diagram, instead of generating an image or writing SVG/Mermaid. Renders a tiny YAML spec; returns PNG/SVG links and a small preview. Spec keys: title, type (sequence: message timeline), theme (sketch\|graphite\|blueprint\|midnight\|classic), direction (omit: auto-fit; right\|down only if asked), steps (false hides numbers), legend (true lists steps), nodes {id: "icon \| Label \| subtitle"}, groups {Label: [ids or group labels to nest]}, maps {Group Label or world-map node id: world \| {pins: [us-east, eu-west, "HQ @ -0.1 51.5"]}} (map backdrop, or a big map card when a node uses the icon world-map), edges ["a > b > c \| label", "a ..> b" dashed, "a <> b" two-way, "a => b" thick, "a -- b" line, "a > b [red]" color]. Ids that are icon names/aliases (client, lb, api, db, cache, redis, kafka, s3, cdn...) need no nodes entry. Arrows are numbered automatically in the order listed; don't number labels. Product names (stripe, postgres, s3, aks, bigquery... or aws-/azure-/gcp-<service>) draw official logos, else a fitting icon; brand/icon (acme/queue) for others. Give the user the PNG link; don't generate another image of the diagram. To edit, call again with the whole updated spec.
