Stack Exchange Cross-Tag Analysis is a small collection of Python scripts to automatically query the most popular tags from all main Stack Exchange sites, index them, and finally create a CSV file with all cross-tag occurences suitable for import into Gephi as well as a JSON file for visualizing the graph with D3.
docker-compose run --rm secta /usr/src/app/update.py updates the JSON and CSV files in the www directory.
docker-compose up -d serves the web visualization on port 8000.
