Here you can find the SageMath code that generates the graphs presented in the preprint "The variance of the number of sums of two squares in Fq[T] in short intervals". The functions F_graphs() and G_graphs() generate Figures 2 and 3, respectively. The function variance_graph() generates Figure 1, but one first must run this MATLAB code in the same folder.
