Pictures for elliptic curves over Q\Q

For each elliptic curve $E$ over $\mathbb{Q}$, the plot displayed is of part of $E(\mathbb{R})$, the set of real points of $E$.

The plots are produced using SageMath, which uses plotting logic designed by David Roe to determine which subset of $E(\mathbb{R})$ in the real affine plane to include in the plot.
