This is a port to JavaScript of some of Mike Chmutov's Java code for the Affine Matrix Ball Construction algorithm.  The original code can be found here: https://github.com/mchmutov/AMBC.  The drawing code and the code to run the webpages are borrowed from the pages on my site:  https://devragj.github.io/.  Two papers describing the Affine Matrix Ball Construction can be found at these links:  Matrix-Ball Construction of affine Robinson-Schensted correspondence, Monodromy in Kazhdan-Lusztig cells in affine type A.  The second paper has a more condensed description of the algorithm.

The first page linked to below runs the AMBC algorithm.  The second page runs the algorithm in reverse.
