Strength and degree distributions for the characters in One Piece. A Strength distribution. B Degree distribution. C The relationship between the degree and strength. Each circle represents a character. The coefficient \(\alpha\) is determined by the linear regression \(\log s_i = \alpha \log k_i +b\), where b is an intercept; the solid line shows the linear regression. Variable \(R^2\) represents the coefficient of determination
