Plot pairs of sequences in the OEIS

The OEIS is supported by the many generous donors to the OEIS Foundation.

Sample pairs of sequences to plot:

X-coordinates plotted against Y-coordinates for certain problems (Suggested by Peter Kagey)

Pairwise plots

A117154 vs A119560 (mathematically obscure but visually interesting - see the link in the latter sequence for more)
A119560 vs A000040
A004055 vs A000040 (Suggested by David Wilson)
Shifted: A108618(n) vs. A108618(n+1), untransformed and without line segments, produces a spiral. (Suggested by Creighton Dement.)

Both sequences against n

A002330 and A002331, A002365 and A002366, A076340 and A076341, with line segments. (Suggested by Franklin Adams-Watters.)
A007305 and A007306 (Suggested by David Wilson)

Ratios

Bernoulli numbers: log(|A027641/A027642|), log(|A000367/A002445|), A050925/A050932
Convergents to sqrt(2): A001333/A000129
1/n!: A000012/A000142
1/n: A000012/A000027
