Whiteboard-Marker-Zeichnung

Create a realistic photograph of an ordinary office or classroom whiteboard carrying a skilled dry-erase marker drawing of the subject described in the user request. Render the artwork as confident hand-drawn linework in a single marker color: a detailed sketch with hatching, varied line weight, and the slightly chalky, semi-translucent quality of marker pigment where strokes overlap and thin out. Near the drawing, add short handwritten caption text in the same marker, in casual all-caps handwriting; take the wording from the user request, or invent a simple fitting label if none is given. Sell the trompe-l'oeil with photographic evidence: a glossy white board surface catching window glare and soft light reflections on one side, faint ghosting of previously erased marks, a thin metallic frame with a marker tray visible at the bottom edge, and a shallow, believable office or classroom depth behind. Keep the photograph neutral and documentary — natural light, true whites, everyday setting. No watermark, no printed logos, no digital-looking vector linework.
