Sample pairs of sequences to plot:

• X-coordinates plotted against Y-coordinates for certain problems (Suggested by Peter Kagey)
• A297346 vs A297347 (Babylonian spiral)
• A293772 vs A293773 (A nice construction of Rémy Sigrist)
• A274369 vs A274370 (Langton's ant)
• A233380 vs A233381 (Greedy brick tiling)
• A305575 vs A305576 (Sort by (r, theta))
• 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
