Fraud Detection Console using IEEE Dataset

Introduction The dashboard is hosted on Render’s free tier: https://ieee-fraud-detection.onrender.com/ (it can take a minute or so to load first time). The data I used the IEEE-CIS Fraud Detection dataset from Kaggle: https://www.kaggle.com/competitions/ieee-fraud-detection/ Of all the fraud-related datasets I found, this seemed one of the most complete, with over half a million rows of data and hundreds of features. The analysis As usual, I used a Marimo notebook. I imported the data and merged the transaction and identity data on the Transaction ID. I also added a column has_identity, as only about a quarter of the transactions had identity data. This keeps identity coverage as an explicit signal, rather than hiding it inside lots of missing identity fields.
