- A request can be rejected without storage or render-count charge; proceeding with a severe finding requires an explicit request.
Field notes
The documented input schema allows five chart types, up to 12 series, and up to 100 points per series. Findings carry a severity and suggested remedy; invalid fields receive a path-specific HTTP 400 response. The page also draws a boundary around the checks: they assess chart structure, not whether the supplied data is accurate.
