The video tutorial explains how to visualize text data using TensorBoard in PyTorch. It covers setting up the environment in Google Colab, including using a GPU and upgrading to TensorFlow 2.1. The tutorial demonstrates loading the IMDb dataset, preparing it for analysis, and logging text data and labels to TensorBoard. Finally, it shows how to view and interpret the logged data in TensorBoard.
