-# 🔍 Interactive Embedding Vector Visualization
-
-EmbeddingBuddy is a web application for interactive exploration and
-visualization of embedding vectors through dimensionality reduction techniques
-(PCA, t-SNE, UMAP).
-
-You have two ways to get started:
-
-1. Generate embeddings directly in the browser if it supports WebGPU.
-2. Upload your NDJSON file containing embedding vectors and metadata.
-
-## Generating Embeddings in Browser
-
-1. Expand the "Generate Embeddings" section.
-2. Input your text data (one entry per line).
-    1. Optionally you can use the built in sample data by clicking "Load Sample Data" button.
-3. Click "Generate Embeddings" to create vectors using a pre-trained model.
-
-## NDJSON File Format
-
