Infographic composite artwork of the Temple of Heaven (Tiantan) in Beijing. Base layer is a high-resolution realistic professional photograph of the Hall of Prayer for Good Harvests and its surrounding park environment, with blue sky, ancient cypress trees, and tourist plazas. Semi-transparent blueprint white chalk-style line sketches overlaid on top of the photo without fully covering the real background. Hand-drawn rectangular box in one corner containing bold handwritten title "TEMPLE OF HEAVEN". Detailed white chalk technical architectural annotations all over the frame, including structural dimension measurements (diameter, height, column counts), raw material quantity data labels (wood, stone, bricks), internal cutaway cross-section diagrams showing the triple-eaved roof structure, layered floor plan sketches of the circular altar and the Imperial Vault of Heaven, load force flow directional arrows showing weight distribution through the 28 pillars, labeled key engineering joints (bracket sets, mortise and tenon connections) and iconic architectural features (triple-eaved circular roof, marble three-tiered base, blue glazed tiles). Blueprint aesthetic, thin clean white chalk sketch lines against realistic photo backdrop. Educational engineering infographic layout. Soft semi-transparent overlay so the real landscape of the Temple of Heaven remains clearly visible behind all drawings. Subtle blueprint light blue tint wash over entire image. Clean technical drafting style, sharp details, 8K, ultra realistic photo base, minimalist chalk sketch overlays, clear text labels, cinematic composition, informational architectural diagram poster.
