Pythagorean tree:

For each natural number $n$, we draw a periodic curve starting from the origin, intersecting the $x$-axis at $n$ and its multiples. The prime numbers are those that have been intersected by only two curves: the prime number itself and one.

Below the currently highlighted number, we also show its sum of divisors $σ(n)$, and its aliquot sum $s(n) = σ(n) - n$, which indicate whether the number is prime, deficient, perfect or abundant.
