+"""
+Enhanced ASHRAE tables module for HVAC Load Calculator, compliant with ASHRAE Handbook—Fundamentals (2017, Chapter 18).
+Provides CLTD, SCL, CLF tables, climatic corrections, and visualization for cooling load calculations.
+Integrates data from ASHRAE Tables 7 (CLTD), 12 (CLF), and other sources for accurate HVAC load calculations.
+
+ENHANCEMENTS:
+- Expanded CLTD tables for walls and roofs at 24°N, 32°N, 36°N, 44°N, 56°N (ASHRAE Table 7).
+- Added interpolation for CLTD and SCL values at intermediate latitudes.
+- Implemented caching for CLTD, SCL, and CLF lookups to optimize performance.
+- Aligned SCL tables to include 44°N explicitly.
+- Added detailed occupancy and equipment heat gain tables for precise internal load calculations.
+- Included climatic corrections for latitude, month, color, and temperature differences.
+- Added visualization of cooling load profiles.
+- Validated data against ASHRAE Handbook—Fundamentals (2017).
