Heat map of TTP elemental correlation coefficients. The vertical axis is the TTP element, and the horizontal axis is the TTP category. The correlation coefficients are normalized and take values between 0 and 1. A correlation coefficient closer to 0 indicates a weaker relationship between the element and the TTPs, and a correlation coefficient closer to 1 indicates a stronger relationship
