Ever wondered which squares on the chessboard see the most action? The ChessFlow Heatmap Visualizer turns your game data into a vibrant map, revealing the "hotspots" of your battle.

By analyzing a PGN file, this tool calculates how frequently each square is visited. Squares that are heavily contested will glow Red, while peaceful areas remain Blue. This visual feedback helps you understand board control and piece activity.

Why Use a Heatmap?

• Identify Key Battles: See exactly where the game was decided.
• Positional Understanding: Learn which squares you tend to control or neglect.
• Data Visualization: A unique way to look at chess beyond just moves.
