2025 Fictional Regional Energy Flow Chord Diagram

Publication-quality data visualization chord diagram mapping fictional 2025 regional energy flows, refined data-journalism aesthetic (no generic infographic styling), bright solid ivory background, perfectly centered circular composition. Harmonious, restricted color palette of cobalt blue, teal, warm ochre, soft coral, deep plum, and graphite gray only. Mathematically precise geometry, smooth clean arcs, semi-transparent non-clashing ribbons where ribbon thickness directly correlates to energy flow volume, balanced uncluttered white space for maximum readability, crisp fully legible sans-serif text throughout.
Top centered title block with bold text "Regional Energy Exchange", smaller subtitle directly below reading "TWh, 2025". Outer ring segments clearly labeled in sequential order: "North", "South", "East", "West", "Coastal", "Grid Reserve". Tiny evenly spaced numeric tick marks around the outer ring marked "0", "50", "100", "150" to denote volume scale. Small unobtrusive legend placed in the bottom right corner with color-coded entries labeled "Hydro", "Solar", "Wind", "Storage".
Ultra high resolution, sharp edges, zero geometric distortion, all text perfectly crisp and readable, balanced visual hierarchy, professional academic/publication level polish.
