# **Embedding Dimension Visualizer**

An **Embedding Dimension Visualizer** is an interactive Streamlit tool designed for teaching and experimentation with modern transformer embeddings. It lets you:

* **Tokenize** any input text using tiktoken or HuggingFace’s BPE tokenizer, showing each subword token and its ID.
* **Visualize embeddings** by generating a demo embedding vector for every token.
* **Compute and display sinusoidal positional encodings** (sin / cos) per token position.
* **Combine embeddings + positional encodings** and present the final per-token vectors exactly as they’d be fed into attention heads.
* **Expose theory** via an expandable section—complete with LaTeX formulas—covering tokenization, BPE, and the positional-encoding equations.
* **Lock sliders** into read-only mode, so learners can observe values without accidentally altering them.

This app is ideal for workshops, live demos, or self-study when you want a hands-on, visual understanding of how embeddings and positional information come together inside a transformer model.
