/annotateddiagram Create an annotated conceptual diagram of the common drinking-water treatment stages described by CDC: coagulation, flocculation, sedimentation, filtration and disinfection. Give each a short role label and a distinct simple schematic. Clearly state that actual treatment differs by source water and community. Do not invent plant equipment, dimensions, chemical quantities, engineering accuracy, or guarantees that these stages remove every contaminant. Label the drawing conceptual and not to scale. Read the official source below before designing. If you cannot open it, ask me to paste the relevant text; do not guess. Show the page date if available and your retrieval date. Use only supported facts and clearly label scope, exceptions, uncertainty and editorial groupings. Treat the slash label as a format request, not an assumed built-in command. Use a clean fine-line editorial style, readable type, ample spacing and labels that do not rely on color alone. Produce the actual visual if your tools support it; otherwise provide an explicitly labeled layout specification. Include the official link, concise alt text, a complete text equivalent and a fact-check list. Do not invent an agency seal, endorsement or product screenshot.
