I just posted a 4 part series on setting up a Flask app on EC2, filling out a database, and visualizing the data with D3.js. The original motivation for this project was to answer the question "What is the latest I can leave work while still having a 90% probability of making my intended BART train?" It grew into these posts, ultimately resulting in a static HTML page that gets data from a Flask app backed by SQL.
