Modify embedding visualiser to display embeddings of genomic data

Original repository https://github.com/harveyslash/TSNE-Embedding-Visualisation is a fork of a Tensoflow tool. It is built to show images as elements of the embedding. For genomic data, it is not meaningful. It would be great if the modified version could show labels associated with embedding vectors.

The issue points to the original TensorFlow embedding visualiser at https://github.com/harveyslash/TSNE-Embedding-Visualisation, but does not name files or tests in this repository. Start by comparing the fork with the original and tracing how embedding points currently display images. Done means the visualiser can display labels associated with genomic embedding vectors instead; the issue gives no test or specific label format.
