oeis.tools: Access and Visualize Integer Sequences from the OEIS
Programmatic access, analysis, and visualization of integer sequences from the On-Line Encyclopedia of Integer Sequences (OEIS) <https://oeis.org>. Fetches sequence metadata and b-files, stores terms as arbitrary-precision integers via 'gmp', and plots them with 'ggplot2'.
