In the KDE plots (Figure ), the entire MOF dataset forms a broad baseline across the four core properties: VF, LCD, PLD, and SA. However, it is noteworthy that most MOFs already lie under ∼10 Å for LCD/PLD and ∼2000 m 2 /g for SA, producing a center-heavy distribution in these properties. Each selection method's curve then reveals how it shifts or narrows this baseline. IPs maintain a moderate width, capturing a broad portion of VF and pore sizes without forming a dominant peak. EI and PI, by contrast, form more pronounced peaks in the high-density region near VF ≈ 0.5-0.7 and typically smaller pore diameters. STD flattens further into the lower-probability zones, indicating that it systematically samples rarer structural motifs.
